%N Array defined by T(i,1)=i, T(1,j)=2j, T(i,j)=T(i-1,j)+T(i-1,j-1) read by antidiagonals.

%C It seems to me that the recurrence should read: T(i,0)=i, T(0,j)=2j, T(i,j)=T(i-1,j)+T(i-1,j-1) rather than T(i,1)=i, T(1,j)=2j, T(i,j)=T(i-1,j)+T(i-1,j-1). Same for the related sequences, otherwise, is T(1,1) = 1 or 2? - Michael Forbes (mforbes(AT)alum.mit.edu), Sep 16 2005
