%N A triangular sequence of polynomial coefficients of an adjusted root product one polynomial set: w(i,n)=If[i == 1, 1/n!, i]; p(x,n)=n!*Product[x - w[i, n], {i, 0, n}]/x.
%C Row sums are:
%C {1, 0, -1, 10, -138, 2856, -86280, 3628080, -203207760, 14631281280, -1316818581120}.
%C The one adjusted roots are:
%C Product[w[i,n],{i,1,n}]=1
%C and
%C sum[Log[w[i,n]],{i,1,n]]=0
%C so that the first and last coefficients of:
%C Product[x - w[i, n], {i, 0, n}]
%C are one. In this specific case the internal coefficients are skew
%C (not symmetrical).
%F w(i,n)=If[i == 1, 1/n!, i]; p(x,n)=n!*Product[x - w[i, n], {i, 0, n}]/x; t(n,m)=coefficients(p(x,n)).
