• Composite n coprime to 5 such that Fibonacci(n) == Legendre(n,5) (mod n).at n=12A049062
• Number of homeomorphically irreducible multigraphs (or series-reduced multigraphs or multigraphs without nodes of degree 2) on 5 labeled nodes.at n=10A060535
• Permutation of N induced by rotating the node 5 left in the infinite planar binary tree shown at A065658.at n=20A065669
• Composite n such that Fibonacci(n) == Legendre(n,5) == -1 (mod n).at n=4A094063
• G.f. satisfies A(x) = 1 + x*(1 + x*A(x)^2)^4.at n=8A137956
• Number of partitions of n in which no parts are multiples of 6.at n=44A219601
• Start with a square of dimension 1 X 1, and repeatedly append along the squares of the previous step squares with half their side length that do not overlap with any prior square; a(n) gives the number of squares appended at n-th step.at n=12A321237
