COMMENT
|
T(g, h, w) = |{m : A062537(m) = g, A109301(m) = h, A001221(m) = w}|.
This is the column that is labeled "r" in the tabulation of A112095.
g = h > 0 implies w = 1 and T(j, j, 1) = 2^(j-1) = A000079(j-1).

EXAMPLE
|
Table T(g, h, w), omitting empty cells, starts out as follows:
g\(h,w) | (0,0) (1,1) (2,1) (2,2) (3,1) (3,2) (4,1) (4,2) (5,1)
