 OFFSET 0,2 COMMENTS Number of partitions of 60n+k, 0<=k<60 into parts <=6 is a polynomial of degree 5 by variable n. LINKS Table of n, a(n) for n=0..23. Index entries for linear recurrences with constant coefficients, signature (6,-15,20,-15,6,-1). FORMULA a(n) = 1 +(167*n +2325*n^2 +15400*n^3 +47250*n^4 +54000*n^5)/6. a(n) = A001402(60*n). G.f.: (3331*x^5+161052*x^4+578757*x^3+317007*x^2+19852*x+1)/(x-1)^6.
