%N Binomial transform of [1, 5, 15, 35, 70, 0, 0, 0, ...].
%C Conjecture: rightmost digit of terms is cyclic: (1, 6, 6, 6, ... repeat).
%F Binomial transform of [1, 5, 15, 35, 70, 0, 0, 0, ...] where (1, 5, 15, 35, 70) = row 4 of triangle A046899.
%F From _R. J. Mathar_, Jul 31 2008: (Start)
%F O.g.f.: (1 + x + 6x^2 + 16x^3 + 46x^4)/(1-x)^5.
%F a(n) = 46 - 200*n + 330*A000217(n) - 245*A000292(n) + 70*A000332(n+3). (End)
%F a(n) = (552 - 1190*n + 895*n^2 - 280*n^3 + 35*n^4)/12. - _T. D. Noe_, Aug 22 2008
%e a(4) = 96 = (1, 3, 3, 1) dot (1, 5, 15, 35) = (1 + 15 + 45 + 35).
