Wang Dianjun and Li Xianhua put forward the following conjectures,respectively:Conjecture Ⅰ: Let M be a finite simple group and C a group, then C ≌ M if and only if πs (G) =πs (M).Conjecture Ⅱ: Let N and M be all nonabelian simple groups. If and | N | | M |, then N ≌ M or N ≌ PSL(2,11) while M ≌ M11.In this short paper, that the conjecture Ⅱ implies the conjecture Ⅰ is proved. Therefore, the proof of the conjecture Ⅰ can be reduced to consider the problem just for simple groups.
