In previous papers, the authors introduced and characterized a class of matrices called {K,s+1}-potent. Also, they established a method to construct these matrices. The purpose of this paper is to solve the associated inverse problem. Several algorithms are developed in order to find all involutory matrices bdd47ccf594b9f4" title="Click to view the MathML source">K satisfying KAs+1K=A for a given matrix ae6e9cc5b796bcacc8430de6774ad" title="Click to view the MathML source">A∈Cn×n and a given natural number 8d5b9aec0bd3da22279abc8c7c86" title="Click to view the MathML source">s.
