   Row sums give A130031(n+1), n>=0. 

   Row sums of unsigned triangle give A130032(n+1),n>=1. 


   Columns sums give, for m=0,1,2:  A010790(n-1)*(-1)^(n-1), A084915(n+1)*(-1)^n, A130033.


   This triangle coincides with triangle A129467 without row n=0 and column m=0 and then taking

   again offset [0,0].
