OEIS Sequences

Number of regions in an equilateral triangular figure formed by the straight line segments connecting all vertices and all points that divide the sides into n equal parts. A92867

Indices k such that s_k(4) is a (probable) prime, where s_k(4) = 4·s_k-1(4) - s_k-2(4), k >= 2, s₀(4) = 1, s₁(4) = 5. A299100

Number of triple-crossings of diagonals in the regular 2n-gon. A260417

Number of curved edges among all distinct circles that can be constructed from the 3 vertices and the equally spaced 3·n points placed on the sides of an equilateral triangle when every pair of the 3 + 3·n points are connected by a circle and where the points lie at the ends of the circle's diameter. A372733

a(n) = (2·n³ + 5·n² - 13·n)/2. A162262

Number of permutations of degree n with barycenter 0. A62868

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of the n*(k+1) boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of regions in the resulting planar graph. A367323

Smallest prime that is the sum of a square and a positive cube in n different ways. A173795
