Abstract
Motivated by a recent paper, in which the authors studied Re-nnd
{1,3}-inverse, {1,4}-inverse and {1,3,4}-inverse of a square matrix, in this
paper, we establish some equivalent conditions for the existence of Re-nnd
{1,2,3}-inverse, {1,2,4}-inverse and {1,3,4}-inverse. Furthermore, some
expressions of these generalized inverses are presented.
