Question 1:Is there a reference that lists all possible orders (or the groups itself up to isomorphism) of finite subgroups of $SO(n)$ and $O(n)$ for $n=4$ or even higher $n$ over the real numbers?

I can only find incomplete lists on wikipedia, mathoverflow or other sources in the internet.

Question 2: Is there a computer algebra package that can list those finite subgroups up to some order? Maybe a package of GAP?
