摘要：

Two Latin squares of order v are r-orthogonal if their superposition produces exactly r distinct ordered pairs. The two squares are said to be r-orthogonal idempotent Latin squares and denoted by r-MOILS(v) if they are all idempotent. In this paper, we show that for any integer v >= 28, there exists an r-MOILS(v) if and only if r is an element of [v, v(2)] \ {v + 1, v(2) - 1}.
