%N Triangle, rows = inverse binomial transforms of A117938 columns.
%C A117936 is the companion triangle using analogous Fibonacci polynomials. Left border of A117936 = the Lucas numbers; right border = factorials.
%C [Note that most of the comments here and in many related sequences by the same author refer to some unusual definition of binomial transforms for sequences starting at index 1.  _R. J. Mathar_, Jul 05 2012]
%F Rows of the triangle are inverse binomial transforms of A117938 columns. A117938 columns are generated from f(x), Lucas polynomials: (1); (x); (x^2 + 2); (x^3 + 3x); (x^4 + 4x + 2);...
%e First few rows of the triangle are:
%e 1;
%e 1, 1;
%e 3, 3, 2;
%e 4, 10, 12, 6;
%e 7, 27, 58, 60, 24;
%e 11, 71, 240, 420, 360, 120;
%e ...
%e For example, row 4: (4, 10, 12, 6) = the inverse binomial transform of column 4 of A117938: (4, 14, 36, 76, 140...), being f(x), x =1,2,3...using the Lucas polynomial x^3 + 3x.
