%N A094617 Triangular array T of numbers generated by these rules: 2 is in T; and 
               if x is in T, then 2x-1 and 3x-2 are in T.
%C A094617 T(n,0)=1+2^n=A000051(n); T(n,n)=1+3^n=A048473(n); T(2n,n)=1+6^n=A062394; 
               row sums = A094618.
%F A094617 To obtain row n from row n-1, apply 2x-1 to each x in row n-1 and then 
               put 1+3^n at the end. Or, instead, apply 3x-2 to each x in row n-1 
               and then put 1+2^n at the beginning.
%e A094617 Rows 0 to 3:
%e A094617 2 = T(0,0)
%e A094617 3 4 = T(1,0) T(1,1), etc.
