[SOLVED] Normalizer & normal subgroup related

Let H \subset G.
Why is H a normal subgroup of its own normalizer in G?
 
Physics news on Phys.org
Sorry for wasting space... I figured it out.
(wasn't reading the definition of normalizers carefully)

It was one of those things that one could attach "Clearly," at the front of the statement.

Unfortunately, this leads to another question...
How do I delete this thread?
