FORMULA
| Let v(3)=(1, 1, 1), let M(3) be the 3 X 3 matrix m(i, j) =min(i, j); then a(n)= min ( v(3)*M(3)^n) - Benoit Cloitre (benoit7848c(AT)orange.fr), Oct 03 2002
GF= -((1 + (-3 + q)*q)/(-1 + (-3 + q)*(-2 + q)*q)). - Wouter Meeussen, Mar 19 2005

PROG
| (PARI) k=3; M(k)=matrix(k, k, i, j, min(i, j)); v(k)=vector(k, i, 1); a(n)=vecmin(v(k)*M(k)^n)
