arity: top to bottom depth: back to front cohort weight: left to right
The sum ignoring cohort weight is triangle Oak. The sum ignoring depth is reflectedAsh.
The layer sums (and row sums of these triangles) are sequence Daisy (A006116).
fixed arity (depth × cohort weight matrices)
The row sums are rows of Oak. The column sums are rows of reflected Ash. The total sums are entries of Daisy.
