Projective special linear group

Particular cases

Some facts:

For $q = 2$ , $PSL(n,q) = SL(n,q) = PGL(n,q) = GL(n,q)$ . For $q$ a power of two, $PSL(n,q) = SL(n,q)$ but this is not equal to $GL(n,q)$ .
Projective special linear group equals alternating group in only finitely many cases: All those cases are listed in the table below.
Projective special linear group is simple except for finitely many cases, all of which are listed below.
