%N A112096 Tetrahedron T(g, h, w) = number of rotes of weight g, height h, wayage w.
%C A112096 T(g, h, w) = |{m : A062537(m) = g, A109301(m) = h, A001221(m) = w}|.
%C A112096 This is the column that is labeled "r" in the tabulation of A112095.
%C A112096 g = h > 0 implies w = 1 and T(j, j, 1) = 2^(j-1) = A000079(j-1).
