Question: What characteristic does Bursaria and Boykinia share>
Sentence (from "Supersingular elliptic curve"): In algebraic geometry, supersingular elliptic curves form a certain class of elliptic curves over a field of characteristic "p" > 0 with unusually large endomorphism rings. Elliptic curves over such fields which are not supersingular are called "ordinary" and these two classes of elliptic curves behave fundamentally differently in many aspects.
Relevant evidence: No
