The groups of type "E"6 over arbitrary fields (in particular finite fields) were introduced by .
The points over a finite field with "q" elements of the (split) algebraic group E6 (see above), whether of the adjoint (centerless) or simply connected form (its algebraic universal cover), give a finite Chevalley group.
This is closely connected to the group written E6("q"), however there is ambiguity in this notation, which can stand for several things:  the finite group consisting of the points over F"q" of the simply connected form of E6 (for clarity, this can be written E6,sc("q") or more rarely formula_16 and is known as the "universal" Chevalley group of type E6 over F"q"),  (rarely) the finite group consisting of the points over F"q" of the adjoint form of E6 (for clarity, this can be written E6,ad("q"), and is known as the "adjoint" Chevalley group of type E6 over F"q"), or  the finite group which is the image of the natural map from the former to the latter: this is what will be denoted by E6("q") in the following, as is most common in texts dealing with finite groups.
From the finite group perspective, the relation between these three groups, which is quite analogous to that between SL("n,q"), PGL("n,q") and PSL("n,q"), can be summarized as follows: E6("q") is simple for any "q", E6,sc("q") is its Schur cover, and E6,ad("q") lies in its automorphism group; furthermore, when "q"−1 is not divisible by 3, all three coincide, and otherwise (when "q" is congruent to 1 mod 3), the Schur multiplier of E6("q") is 3 and E6("q") is of index 3 in E6,ad("q"), which explains why E6,sc("q") and E6,ad("q") are often written as 3·E6("q") and E6("q")·3.
From the algebraic group perspective, it is less common for E6("q") to refer to the finite simple group, because the latter is not in a natural way the set of points of an algebraic group over F"q" unlike E6,sc("q") and E6,ad("q").
Beyond this “split” (or “untwisted”) form of E6, there is also one other form of E6 over the finite field F"q", known as 2E6, which is obtained by twisting by the non-trivial automorphism of the Dynkin diagram of E6.
Concretely, 2E6("q"), which is known as a Steinberg group, can be seen as the subgroup of E6("q"2) fixed by the composition of the non-trivial diagram automorphism and the non-trivial field automorphism of F"q"2.
Twisting does not change the fact that the algebraic fundamental group of 2E6,ad is Z/3Z, but it does change those "q" for which the covering of 2E6,ad by 2E6,sc is non-trivial on the F"q"-points.
Precisely: 2E6,sc("q") is a covering of 2E6("q"), and 2E6,ad("q") lies in its automorphism group; when "q"+1 is not divisible by 3, all three coincide, and otherwise (when "q" is congruent to 2 mod 3), the degree of 2E6,sc("q") over 2E6("q") is 3 and 2E6("q") is of index 3 in 2E6,ad("q"), which explains why 2E6,sc("q") and 2E6,ad("q") are often written as 3·2E6("q") and 2E6("q")·3.
Two notational issues should be raised concerning the groups 2E6("q").
One is that this is sometimes written 2E6("q"2), a notation which has the advantage of transposing more easily to the Suzuki and Ree groups, but the disadvantage of deviating from the notation for the F"q"-points of an algebraic group.
Another is that whereas 2E6,sc("q") and 2E6,ad("q") are the F"q"-points of an algebraic group, the group in question also depends on "q" (e.g., the points over F"q"2 of the same group are the untwisted E6,sc("q"2) and E6,ad("q"2)).
The groups E6("q") and 2E6("q") are simple for any "q", and constitute two of the infinite families in the classification of finite simple groups.
Their order is given by the following formula : formula_17 formula_18 .
The order of E6,sc("q") or E6,ad("q") (both are equal) can be obtained by removing the dividing factor gcd(3,"q"−1) from the first formula , and the order of 2E6,sc("q") or 2E6,ad("q") (both are equal) can be obtained by removing the dividing factor gcd(3,"q"+1) from the second .
The Schur multiplier of E6("q") is always gcd(3,"q"−1) (i.e., E6,sc("q") is its Schur cover).
The Schur multiplier of 2E6("q") is gcd(3,"q"+1) (i.e., 2E6,sc("q") is its Schur cover) outside of the exceptional case "q"=2 where it is 22·3 (i.e., there is an additional 22-fold cover).
The outer automorphism group of E6("q") is the product of the diagonal automorphism group Z/gcd(3,"q"−1)Z (given by the action of E6,ad("q")), the group Z/2Z of diagram automorphisms, and the group of field automorphisms (i.e., cyclic of order "f" if "q"="pf" where "p" is prime).
The outer automorphism group of 2E6("q") is the product of the diagonal automorphism group Z/gcd(3,"q"+1)Z (given by the action of 2E6,ad("q")) and the group of field automorphisms (i.e., cyclic of order "f" if "q"="p""f" where "p" is prime). 
The "Q"-function is well tabulated and can be computed directly in most of the mathematical software packages such as Matlab and Mathematica.
The points over a finite field with "q" elements of the (split) algebraic group E7 (see above), whether of the adjoint (centerless) or simply connected form (its algebraic universal cover), give a finite Chevalley group.
This is closely connected to the group written E7("q"), however there is ambiguity in this notation, which can stand for several things:  the finite group consisting of the points over F"q" of the simply connected form of E7 (for clarity, this can be written E7,sc("q") and is known as the “universal” Chevalley group of type E7 over F"q"),  (rarely) the finite group consisting of the points over F"q" of the adjoint form of E7 (for clarity, this can be written E7,ad("q"), and is known as the “adjoint” Chevalley group of type E7 over F"q"), or  the finite group which is the image of the natural map from the former to the latter: this is what will be denoted by E7("q") in the following, as is most common in texts dealing with finite groups.
From the finite group perspective, the relation between these three groups, which is quite analogous to that between SL("n", "q"), PGL("n", "q") and PSL("n", "q"), can be summarized as follows: E7("q") is simple for any "q", E7,sc("q") is its Schur cover, and the E7,ad("q") lies in its automorphism group; furthermore, when "q" is a power of 2, all three coincide, and otherwise (when "q" is odd), the Schur multiplier of E7("q") is 2 and E7("q") is of index 2 in E7,ad("q"), which explains why E7,sc("q") and E7,ad("q") are often written as 2·E7("q") and E7("q")·2.
From the algebraic group perspective, it is less common for E7("q") to refer to the finite simple group, because the latter is not in a natural way the set of points of an algebraic group over F"q" unlike E7,sc("q") and E7,ad("q").
As mentioned above, E7("q") is simple for any "q", and it constitutes one of the infinite families addressed by the classification of finite simple groups.
Its number of elements is given by the formula : formula_13 The order of E7,sc("q") or E7,ad("q") (both are equal) can be obtained by removing the dividing factor gcd(2, "q"−1) .
The Schur multiplier of E7("q") is gcd(2, "q"−1), and its outer automorphism group is the product of the diagonal automorphism group Z/gcd(2, "q"−1)Z (given by the action of E7,ad("q")) and the group of field automorphisms (i.e., cyclic of order "f" if "q" = "pf" where "p" is prime).
