a(n) = floor(n*φ11), where φ is the golden ratio, A001622. A4926
Binomial transform of primes. A7443
Number T(n,k) of equivalence classes of ways of placing k 4 X 4 tiles in an n X n square under all symmetry operations of the square; irregular triangle T(n,k), n>=4, 0<=k<=floor(n/4)2, read by rows. A236757
a(n) = number of steps to reach 0 when starting from k = (n3)-1 and repeatedly applying the map that replaces k with k - A055401(k), where A055401(k) = the number of positive cubes needed to sum to k using the greedy algorithm. A261228
