OEIS Sequences

Values of n for which pi_4,3(p_n) - pi_4,1(p_n) = -1, where p_n is the n-th prime and pi_m,a(x) is the number of primes <= x which are congruent to a (mod m). A51024

Integers k for which {prime(1), prime(2), ..., prime(k)} (mod 4) is biased towards 1. A96628

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n·k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of regions in the resulting planar graph. A367304

Number of -n..n arrays x(0..3) of 4 elements with zeroth through 3rd differences all nonzero. A199945

T(n,k)=Number of -k..k arrays x(0..n-1) of n elements with zeroth through n-1st differences all nonzero. A199943

a(n) = ∑_{d∣n, d==1 (mod 4)} d⁴. A50448

Number of length-n 0..5 arrays with no repeated value differing from the previous repeated value by other than plus two, zero or minus 1. A269616
