%N A147563 A scaled Bernstein-type polynomial set based on A008292 Eulerian numbers: 
               p(x,n)=4*Sum[A0008292[[n]][[m + 1]]*(x/2)^(n - m - 1)*(1 - x/2)^m, 
               {m, 0, n - 1}]
%C A147563 The row sums are: {4, 4, 6, 12, 30, 90, 315, 1260, 5670, 28350, 155925,
               ...}. The Eulerian number scaling is based on the quadratic Sierpinski 
               number: (1,2*k,1}: to give a Bernstein Sierpinski probability scale 
               of: p=x/2*(k-1). Here k=2 so k-1 is 2; for Pascal it is k=1 or 2^0.
%F A147563 p(x,n)=4*Sum[A0008292[[n]][[m + 1]]*(x/2)^(n - m - 1)*(1 - x/2)^m, {m, 
               0, n - 1}]; t(n,m)=coefficients(t(n,m)).
