Again, this is a homework problem, so please don't give me a full solution.
I have not tried this problem as yet, but I am posting ahead of time, just in case i will need help with it. It seems pretty straight forward from the wording, but oh, well, you never know, i'm stupid sometimes...
if no one replies, i'll tell you if i get it or not. i won't look at the hints given until i try the problem myself (after i read the chapter in the book).
Here goes, short and sweet
Determine the group symmetries of a regular pentagon. (It will have order 10.)
As i said, i have not read the chapter, so i have no background info for you guys.
EDIT: oh wait! i see. this is counted in the reflections about the axis... thanks
