%N A111799 Triangle T(h, w) = number of rotes of height h and wayage w.
%C A111799 T(h, w) = |{positive integers m : A109301(m) = h and A001221(m) = w}|.
%C A111799 Let c(h) = 1 for h = 0 and A050924(h) for h > 0. In other words, c(h) is the sequence [1, A050924] = [1,1,2,9,10^9, ...] that begins with 1 and continues with the terms of A050924. Then the number of nonzero entries in row h is c(h) and their sum is A109300(h). See A111798 for definitions and further details.
