COMMENTS
| Sequence gives X values. To find Y values: b(n)=c(n)*(-1+d(n))which gives: 0,4,480,47916,4704000,461030324,45177121440,...

FORMULA
| a(n)=c(n)*(1+d(n)) with c(0)=0,c(1)=1 and c(n)=10*c(n-1)-c(n-2) d(0)=1,d(1)=5 and d(n)=10*d(n-1)-d(n-2)
For n>=4, a(n) = 108*a(n-1) - 982*a(n-2) + 108*a(n-3) - a(n-4) [From Max Alekseyev (maxale(AT)gmail.com), Nov 13 2009]
