Show that every finite group of order n is isomorphic to a group consisting of n x n permutation matrices under matrix multiplication.
(A permutation matrix is one that can be obtained from an identity matrix by reordering its rows)
I can't even understand the question. I think a group of n x n permutation matrices is not isomorphic to finite group of order n. I think it is isomorphic to Sn.
Help me plz!
