COMMENTS

Sequence gives X values. To find Y values: b(n)=c(n)*(-1+d(n))which gives: 0,12,2688,526500,102208512,19828902588,...

FORMULA

a(n)=c(n)*(1+d(n)) with c(0)=0,c(1)=2 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) [From Max Alekseyev (maxale(AT)gmail.com), Nov 13 2009]
