• Expansion of 1/(1-x^4-x^5-x^6-x^7-x^8-x^9-x^10-x^11-x^12).at n=41A017834
• a(n) is the smallest positive integer not yet in the increasing sequence that is obtained when the largest digit from a(n-1) is deleted and the remaining digits are permuted such that no digit in a(n) has the same position it had in a(n-1) (counting from left to right). No repeated digits allowed; a(1)=10.at n=21A302095
• Triangle read by rows: T(n,k) is the number of unlabeled graphs with n nodes and packing chromatic number k, 1 <= k <= n.at n=40A363043
