q-factorial numbers 3!_q. A69778

p(p²-p+1) as p runs through the primes. A83558

a(n) = nonnegative value y such that (A155135(n), y) is a solution to the Diophantine equation x³+28·x² = y². A155137

a(n) = nonnegative value y such that (A155136(n), y) is a solution to the Diophantine equation x³+28·x² = y². A155138

60-gonal (hexacontagonal) numbers: a(n) = n(29n - 28). A249911

a(0) = 0, a(1) = a(2) = 1, a(3) = 2, a(4) = 4, a(5) = 8, a(6) = 16, for n>5: a(n+1) = SORT[ a(n) + a(n-1) + a(n-2) + a(n-3) + a(n-4) + a(n-5) + a(n-6)], where SORT places digits in ascending order and deletes 0's. A108567
