To find Y-values: with c(n) and d(n) as defined in the Formula section, b(n) = c(n)*(-1+d(n)), which gives 0, 6, 1344, 263250, 51104256, 9914451294, ...

Index entries for linear recurrences with constant coefficients, signature (208,-2718,208,-1).
FORMULA
a(n) = c(n)*(1+d(n)) with c(0)=0, c(1)=1 and c(n) = 14*c(n-1) - c(n-2); d(0)=1, d(1)=7 and d(n) = 14*d(n-1) - d(n-2).
For n >= 4, a(n) = 208*a(n-1) - 2718*a(n-2) + 208*a(n-3) - a(n-4). - Max Alekseyev, Nov 13 2009
