• a(n) = 11*3^n - 2*n - 10.at n=8A116972
• Number of fixed poly-[4.6.12]-tiles (holes allowed) with n cells (division into triangles is significant).at n=11A197464
• Strictly superdiagonal compositions: compositions (p1, p2, p3, ...) of n such that pi > i.at n=45A238874
• Triangle read by rows: T(n,k) is the number of bargraphs of semiperimeter n having k levels. A level in a bargraph is a maximal sequence of two or more adjacent horizontal steps; it is preceded and followed by either an up step or a down step.at n=43A273344
