<general linear group> over a <finite field> of order $m$. Remember that due to the <classification of finite fields>, there is one single field for each <prime power> $m$.
Exactly as over the <real numbers>, you just put the finite field elements into a $n \times n$ matrix, and then take the invertible ones.
