T(n,k)=Number of (n+2)X(k+2) 0..3 arrays with no element unequal to a strict majority of its horizontal, vertical, diagonal and antidiagonal neighbors, with values 0..3 introduced in row major order. A231441

Number of partitions of n such that (greatest part) - (least part) > number of parts. A237833

Numbers n such that A182134(n) = 3, i.e., there exist only three primes p with prime(n) < p < prime(n)^{1 + 1/n}. A246781

a(1) = 2, and for n>1: a(n) = prime(A251719(n)) * prime(A251719(n) + n - 2), where prime(n) gives the n-th prime. A251724

a(n) is the number of vertices formed by n-secting the angles of an equilateral triangle. A335411
