 OFFSET 0,2 COMMENTS Original definition: Triangle read by rows in which row n gives the number of equal configurations under cyclic shift. T(n,k) = A051168(n+3,k+1), if 0=n-1, 0, A=x*O(x^n) + y*O(y^n); ps=1-x-y+A; for(m=1, n, for(i=0, m, c=polcoeff(polcoeff(ps, i, x), m-i, y); if(m==n&i==k, break(2), ps*=(1-y^(m-i)*x^i+A)^c))); -c) /* Michael Somos, Jul 17 2004 */ CROSSREFS Row sums give A093210. Essentially the same as A051168. See A185158 for another version.
