OEIS Sequences

Start with a single hexagon; at n-th generation add a hexagon at each expandable vertex (this is the "vertex to side" version); a(n) is the sum of all label values at n-th generation. (See comment for construction rules.) A247905

Capped binary boundary codes for fusenes (all orientations and rotations included). A258012

Numbers m such that Stern polynomial B(m,x) has no irreducible polynomial factors that themselves are Stern polynomials. The initial a(1) = 1 is included by convention. A389918

a(n) = n³ + 4·n² - 5·n + 1. A241577
