• Fibonacci sequence beginning 0, 22.at n=17A022356
• At stage 1, start with a unit equilateral equiangular triangle. At each successive stage add 3*(n-1) new triangles around outside with edge-to-edge contacts. Sequence gives number of triangles (regardless of size) at n-th stage.at n=42A064412
• Structured triakis octahedral numbers (vertex structure 4).at n=21A100171
• Expansion of Product_{k>=1} (1 + x^k*A005185(k)).at n=28A147879
• Number of binary strings of length n with no substrings equal to 0001 0101 or 1011.at n=18A164473
• Numbers n with property that n^2 contains "1234" as a substring.at n=20A175464
• Number of partitions of n such that (greatest part) + (least part) <= number of parts.at n=43A237823
