T(n,k) = Number of n X k 0..2 arrays with no element unequal to a strict majority of its horizontal and antidiagonal neighbors, with the exception of exactly one element, and with new values introduced in order 0 sequentially upwards. A280398

a(n) is the smallest integer k such that the n-th (backward) difference of the partition sequence A000041 is positive from k onwards. A155861

Solution (a(n)) of the complementary equation a(n) = 2·a(n-1) - a(n-2) + b(n-1) + b(n); see Comments. A305330

a(n) is the number of edges formed by n-secting the angles of a hexagon. A335735
