摘　　要：In the author＇s Ph. D thesis, a non-quasiprimitive graph admitting a quasiprimitive automorphism group isomorphic to J1 was constructed ,where J1 is Janko simple group of order 175560. Is this the only one for J1？ In this paper all primitive （J1,2）-arc transitive graphs Г are given and that AutГ≌J1 is proved.In the author＇s Ph.
