FORMULA
Binomial transform of [1, 3, 4, 0, 2, 0, 2, 0, 2, ...].
From R. J. Mathar, Apr 04 2012: (Start)
G.f. 1 + x*(4 - 9*x + 3*x^2) / ( (2*x-1)*(x-1)^3 ).
a(n) = 2^n + n^2 + 2*n-1, n > 0. (End)
EXAMPLE
a(3) = 22 = sum of row 3 terms of triangle A132071: (4 + 7 + 7 + 4).
a(3) = 22 = (1, 3, 3, 1) dot (1, 3, 4, 0) = (1 + 9 + 12 + 0).
