Ecetondudex

The ecetondudex is equal to E303#1#3 = E303#(E303#1#2) = EE...EE303 (ecetondex E's) = 101010...1010303 (ecetondex 10's), using Hyper-E Notation. The term was coined by Sbiis Saibian.
== Etymology ==
The name "ecetondudex" can be separated into 3 parts, "eceton" (means 10303), "du" (which means 2) & "dex"s, where "-dex" means En#n#2, so 2 "-dex"s means the operation applying 2 times.
