- Expansion of e.g.f.: sech(arctanh(x)+log(x+1))=1-4/2!*x^2+6/3!*x^3+45/4!*x^4-300/5!*x^5...at n=10A013166
- Triangle read by rows. Let g(n) = n if n is a prime, otherwise g(n) = 1. Let p(0) = 1, p(n) = g(n)*p(n-1). Row n gives coefficients of Product_{j=0..n} (x - p(j)), with row 0 = {1}.at n=44A118686
- Number of functions f:{1,2,...,n}->{1,2,...,n} such that Im(f) contains 6 fixed elements.at n=3A126781
- Product of primorials of consecutive integers (second definition A034386).at n=7A328946
- a(n) = Product_{k=0..n} (5*k)! / k!^5.at n=2A367569
- Numbers that set records in in A379772.at n=27A379773
- a(n) is the least positive integer k such that the points (p_i, e_i) lie on a straight line with nonzero slope, where p_1^e_1*...*p_n^e_n is the canonical prime factorization of k.at n=3A389339
