 OFFSET 0,1 COMMENTS Continued fraction expansion of (4047+sqrt(16394397))/142. Inverse binomial transform of 57 followed by 128*A000079. Third inverse binomial transform of A176635. LINKS FORMULA a(n) = 64-7*(-1)^n. a(n) = -a(n-1)+128 for n > 0; a(0) = 57. a(n) = a(n-2) for n > 1; a(0) = 57, a(1) = 71. G.f.: (57+71*x)/((1-x)*(1+x)).
