OEIS Sequences

The number of regions formed when every pair of n points, placed at the vertices of a regular n-gon, are connected by a circle and where the points lie at the ends of the circle's diameter. A358782

Numbers n such that φ(n)=2*φ(n-1). A171271

S₁₁ sequence in partition of integers > 1 described in A240521. A241024

Let G_n denote the planar graph defined in A358746 with the addition, if n is odd, of the circle containing the initial n points; sequence gives the number of regions in G_n. A370976

Odd numbers k that can be factored to such a pair of coprime factors·and y that A347381(k) < min(A347381(x), A347381(y)). A347390

After the initial 1, numbers k such that A347381 obtains its minimum value at k, of all the divisors d of k larger than one, where A347381 is the distance from n to the nearest common ancestor of n and σ(n) in the Doudna-tree (A005940). A374218

a(0) = 0, and for n > 0, (a(n)) gives the indices n for which d(n) < d(k) for k < n, where d is the difference sequence of (cos k + sin k). A299640
