Index entries for linear recurrences with constant coefficients, signature (4,0,-20,20,36,-64,-20,90,-20,-64,36,20,-20,0,4,-1).
FORMULA
G.f.: 1 / ((1-x)^4 * (1-x^2)^6).
a(n) = ((8+n)*(2835*(1739+309*(-1)^n) + 576*(15259+1029*(-1)^n)*n + 36*(166171+3717*(-1)^n)*n^2 + 448*(4661+27*(-1)^n)*n^3 + 14*(29749+27*(-1)^n)*n^4 + 49280*n^5 + 3416*n^6 + 128*n^7 + 2*n^8)) / 46448640. - Colin Barker, Jan 15 2017
