摘要
Motivated by the equivalent conditions for the inclusions A(n){1,2,i}...A(2){1,2,i}A(1){1,2,i} subset of (A(1)A(2)...A(n)){1,2,i} (i = 3,4) presented in [B. Zheng and Z. Xiong. The reverse order laws for {1,2,3}- and {1,2,4}-inverses of multiple matrix products. Linear Multilinear Algebra, 58:765-782, 2010.], we show that for i is an element of {3,4}, A(n){1,2,i}...A(2){1,2,i}A(1){1,2,i} = (A(1)A(2)...A(n)){1,2,i} is equivalent to A(n){1,2,i}...A(2){1, 2,i}A(1){1,2,i} subset of (A(1)A(2)...A(n)){1,2,i}.
