A=(a_ij) ∈R~(n×n ) is termed bisymmetric matrix if We denote the set of all n × n bisymmetric matrices by BSR~(n×n ) In this paper, we discuss the following two problems: Problem I. Given X, Find such that Problem Ⅱ. Gived . Find such that where ||·|| is Frobenius norm, and S_E is the solution set of Problem I. The general form of S_E has been given. The necessary and sufficient conditions have been studied for the special cases AX = B and AX = XA of problem I. For problem Ⅱ the expression of the solution has been provided.
