OEIS Sequences

The number of vertices inside a hexagon formed by the straight line segments mutually connecting all vertices and all points that divide the sides into n equal parts. A330846

Primes p such that 54·p-1, 54·p+1 and 60·p-1, 60·p+1 are twin primes. A138698

Beginning with 13, least prime such that concatenation of first n terms and its digit reversal both are primes. A382898

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

a(n) = sum of the products of taking n-1 numbers from the next n numbers. The next n numbers can be grouped like this (1), (2,3), (4,5,6), (7,8,9,10),... and a(n) is the (sum of the reciprocals of all members) multiplied by (the product of all members). A80473
