The problem was originally posed by Molnar in [molnar1974matrix].

Various authors followed up this article with both single solutions and parametric families of solutions:

• American Mathematical Monthly, 82, pages 999-1000, 1975.
• American Mathematical Monthly, 84, page 809, 1977.
• American Mathematical Monthly, 94, page 962, 1987.

Guy presents an overview and discusses variants of the problem [guy2004unsolved].

A CSP model is presented in [frisch2003constraints]
