%N A085484 Symmetric square table, read by antidiagonals, such that the main diagonal 
               is equal to the first row shift left: T(0,0)=1, T(0,k) = sum(m=0,
               k-1, C(k-1,m)*T(m,k-1-m)) when k>0; and T(n,k) = T(n-1,k) + T(n,k-1) 
               when n>0, k>0.
%C A085484 Antidiagonal sums give A085486. First row is A085485; table is symmetric 
               under transpose, so that first column equals the first row. Second 
               row gives partial sums of first row.
