OEIS Sequences

Total number of vertices formed by intersections among sides and straight "chords" in a right triangle when each side is divided by vertices into n equal segments. A274585

Positions of pandigital 10-digit numbers after the decimal point in the decimal expansion of π. A280183

Interprimes which are of the form s·prime, s=19. A75294

Consider a decimal number of k>=2 digits z = d_k*10^k-1 + d_k-1*10^k-2 + ... + d₂*10 + d₁ and the sum y = ∑_x=2..k {∑_j=1..k-x{d_j+x-1*10^j-1} - ∑_j=1..x-1{d_j*10^j-1}}. Sequence lists the numbers for which y = τ(z), where τ(z) is the number of divisors of z. A248904

Third spoke of a hexagonal spiral. A56107

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 vertices in the resulting planar graph. A367322
