A classification of isogeny‐torsion graphs of Q‐isogeny classes of elliptic curves
Let E be a Q-isogeny class of elliptic curves defined over Q. The isogeny graph associated to E is a graph which has a vertex for each elliptic curve in the Q-isogeny class E, and an edge for each cyclic Q-isogeny of prime degree between elliptic curves in the isogeny …
