A monomial matrix with entries in a field is an matrix with exactly one nonzero entry in each row and exactly one nonzero entry in each column. Under matrix multiplication, monomial matrices form a group; this group is isomorphic to a wreath product
with respect to the canonical action of the permutation group on the power of the group of nonzero scalars.
The special case where the non-vanishing entries are 1 is permutation matrices
