Re: Abstrat Algebra Sylow Subgroup Ok but in the case of the order of G is 180. Suppose that P,P' are 3 Sylow subgroup and let Q be there intersection and N the normalizer of Q. Explain why is the order of N divisible by 9 ?Thanks :-)

Re: Abstrat Algebra Sylow Subgroup Thanks for your answer but what is NG(P)=G please ?

I have a question about abstract algebra so if someone could help me answering this question please ... Suppose P,P' are 3-Sylow subgroup, and let Q be their intersection and N the normalizer of Q. Problem: Explain why is the order of N divisible by 9 ? Thanks for your help. Regards,
