Abstract
In this paper we elucidate a connection between linear preservers on coordinate subspaces that permute the elements of a matrix and diagonal hypergraph isomorphisms. Under certain circumstances, the only permutation linear preservers are the special ones which permute rows and columns, and possibly interchange rows with columns as well.
