Numbers n such that n!! + 2 is prime. A76185

Binomial transform of A015128. A266497

Numbers k such that A003415(k) == A276085(k) (mod 2310), where A003415 is the arithmetic derivative and A276085 is the primorial base log-function. A391864

a(n) = first term that can be reduced in n steps via repeated interpretation of a(n) as a base b+1 number where b is the largest digit of a(n), such that b is always 5 so that each interpretation is base 6. Terms already fully reduced (i.e., single digits) are excluded. A141839

Determinant of M(n), the n X n matrix defined by m(i,i) = 1, m(i,j) = i-j. A79034

a(n) = 52·n² + 1. A158644
