Résumé :	In the present paper, the authors explore sub-defects for four classes of doubly substochastic matrices each displaying a certain type of symmetry, namely (1) symmetric matrices (i.e., matrices that are equal to their transpose, obtained by reflecting the original matrix with respect to the main diagonal), (2) Hankel symmetric matrices (i.e., matrices that are equal to their Hankel transpose, obtained by reflecting the original matrix with respect to the main antidiagonal), (3) centrosymmetric matrices (i.e., matrices that are equal to the matrix obtained by rotating the original matrix by 180 degrees), and (4) matrices that are simultaneously symmetric, Hankel symmetric and centrosymmetric.
