File:Z2^4; Lattice of subgroups Hasse diagram adjacency matrix (rearranged by digit sum).svg

67x67 matrix, showing the finer than relation between the partitions shown in File:Boolean partition matrices.svg.

This matrix shows the same relation as File:Boolean partition lattice 4.svg, but the elements are rearranged in a different order, according to their digit sum. For digit sums except 4 the order is the same as in File:Boolean partition matrices top lines by digit sum.svg.

This matrix is nearly symmetrical to the subdiagonal. Apart from the centered rows and columns 33, 34 and 37 (slightly shaded in gray) it is symmetrical to the subdiagonal. With only one of these shaded rows and columns it's still symmetrical.
