Let J2 be th e set of n X n co mpl ex matrices A = (aij) suc h that ajJ,aj,j, . . .aj';' = 0 for all r such th at 3 ,,;;; r ";;; n a nd all distin ct j" j2, . . ., j,.Then many properties of this se t are given , which may be rega rded as gene ralizations of the prope rties of th e set of triple diagonal matrices.
