%N A115195 Triangle of numbers, called Y(1,2), related to generalized Catalan numbers 
               A062992(n)=C(2;n+1)=A064062(n+1).
%C A115195 This triangle Y(1,2) appears in the totally asymmetric exclusion process 
               for the (unphysical) values alpha=1, beta=2. See the Derrida et al. 
               refs. given under A064094, where the triangle entries are called 
               Y_{N,K} for given alpha and beta.
%C A115195 The main diagonal (M=1) gives the generalized Catalan sequence C(2,n+1):=A064062(n+1).
%C A115195 The diagonal sequences give A064062(n+1), 2*A084076, 4*A115194, 8*A115202, 
               16*A115203, 32*A115204 for n+1>= M=1,..,6.
