%N A064094 Triangle composed of generalized Catalan numbers.
%C A064094 The column m sequence (without leading zeros and the first 1) appears 
               in the Derrida et al. 1992 reference as Z_{N}=Y_{N}(N+1), N >=0, 
               for alpha = m, beta = 1 (or alpha = 1, beta = m). In the Derrida 
               et al. 1993 reference the formula in eq. (39) gives Z_{N}(alpha,beta)/
               (alpha*beta)^N for N>=1.
%C A064094 The column sequences (without leading zeros) are: A000012, A000108, A064062-3, 
               A064087-93 for m=0..10, respectively. Row sums give A064095.

               asymmetric exclusion model with open boundaries, J. Stat. Phys. 69,

               A 26, 1993, 1493-1517; eq. (39), p. 1501, also appendix A1, (A12) 
               p. 1513.
%F A064094 G.f. for column m: (x^m)/(1-x*c(m*x))= (x^m)*((m-1)+m*x*c(m*x))/(m-1+x) 
               with the g.f. c(x) of Catalan numbers A000108.
%F A064094 a(n, m)= sum((n-m-k)*binomial(n-m-1+k, k)*(m^k)/(n-m), k=0..n-m-1) =

               1; a(n, n)=1; a(n, m)=0 if n<m; with C(k)=A000108(k) (Catalan).
