Hello! I have this problem:(adsbygoogle = window.adsbygoogle || []).push({});

If H is a subgroup of prime index in a finite group G, show that either H is a normal subgroup or N(H) = H.

What does N(H) means? I don't want a solution for the problem (at least not yet), I just want to know what that notation means. Thank you!
