The 6-by-6 matrices for septrights often contain many zeroes. Serving as examples below are six matrices representing the singletons, each with a checkerboard pattern of zeros, here shown as empty gray squares for de-emphasis. Further, each matrix displays 6 zeroes that are not part of the checkerboard.

The matrix for any qsu3 or rtv3 septright will also reveal the checkerboard pattern.

Matrices q₁ through v₁ are nearly symmetric, with deviations highlighted in yellow. Within each matrix, those deviations appear in only one row and one column.

A gray square implicitly contains zero.
