%N A123315 Pascrabble triangle, read by rows.
%C A123315 The apex of the triangle is 1. Any other value is the Scrabble value 
               of English name for the number which is the sum of the numbers above. 
               This is generated the same way as A007318 Pascal's triangle read 
               by rows, except apply A113172 to each sum. The first column of this 
               triangle is 1, 3, 8, 9, 4, 7, 8, 9, 4, 7, 8, 9, 4, 7... = iterations 
               1, A113172(1), A113172(A113172(1)), A113172(A113172(A113172(1))). 
               The central pascrabble numbers T(2n+1,n) = 1, 10, 19, 21, 18, 11, 
               22, ...
%F A123315 T(1,1) = 1; for i > 1, T(i,j) = A113172(T(i-1, j-1)+T(i-1, j).
