 Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 60th year, we have over 367,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”). Other ways to Give

 OFFSET 0,2 LINKS Colin Barker, Table of n, a(n) for n = 0..700 Index entries for linear recurrences with constant coefficients, signature (33,-236,492,-288). FORMULA O.g.f.: 1/((1 - x)*(1 - 2*x)(1 - 6*x)*(1 - 24*x)). From Colin Barker, Feb 02 2018: (Start) a(n) = (-11 + 115*2^n - 759*6^n + 1920*24^n) / 1265. a(n) = 33*a(n-1) - 236*a(n-2) + 492*a(n-3) - 288*a(n-4) for n>3.
