%N A symmetrical triangle between the Eulerian numbers, A008292, and MacMahon numbers, A060187, by linear combination with Pascal(A007318), Eulerian numbers ,and Narayana numbers,A001263,:k=3;t(n,m,k)=Binomial[n, m] - k*(Binomial[n, m]*Binomial[n + 1, m]/(m + 1)) + k*Eulerian[n + 1, m]
%C Row sums are:
%C {1, 2, 7, 38, 250, 1796, 13897, 116798, 1074310, 10836524, 119575066,...}.
%C By solving the linear combination of Pascal,Narayana and Eulerian to give
%C the MacMahon at k=4, I got this functional set of symmetrical triangles.
%C By modulo two pattern the k=3 set is Narayana numbers like and the k=6 ,{1.8.1} level,
%C is a new even Sierpinski type.
