- Sum of divisors of Ramanujan's highly composite numbers, or sigma(A002182(n)).at n=26A063072
- Numbers n such that (i) the largest prime factor of n is not a palindrome and (ii) the sum of the factorials of the digits of n is equal to the largest prime factor of n reversed.at n=28A074301
- Let f(k) denote the largest prime factor of k which is not a palindrome. Sequence gives numbers k such that the sum of the factorials of the digits of k is equal to f(k) reversed.at n=29A111185
- a(n) = sum of divisors of A094348(n).at n=29A182941
- Numbers n with property that n and 2n are sums of two distinct positive cubes.at n=33A191345
- Integers n such that each of n, 2n and 3n is a sum of 2 distinct positive cubes.at n=8A191383
- Consider numbers n = concat(w,x,y,z) such that w*x*y*z | n. Leading zeros in x, y and z allowed. Sequence lists numbers that admit at least two such concatenations.at n=32A257172
- Numbers m having greatest prime power divisor d such that d is smaller than the difference between m and the largest prime smaller than m and d is smaller than the difference between m and twice the largest prime smaller than m/2.at n=34A290290
