- Numbers k such that k and k^2 use only the digits 1, 2, 3 and 5.at n=19A136973
- Numbers k such that k and k^2 use only the digits 1, 2, 3, 5 and 7.at n=39A136975
- Numbers k with d digits such that all digits of k and the last d+1 digits of k^2 are prime.at n=21A154780

- For a positive number k, let L(k) denote the list consisting of k followed by the prime factors of k, with repetition, in nondecreasing order; sequence gives composite k such that the digits of L(k) are in nondecreasing order.at n=16A372029
- For a positive number k, let L(k) denote the list consisting of k followed by the prime factors of k, with repetition, in nondecreasing order; sequence gives k such that the digits of L(k) are in nondecreasing order.at n=22A372055
- For a positive number k, let L(k) denote the list consisting of k followed by the prime factors of k, with repetition, in nondecreasing order; sequence gives composite k such that the digits of k is either 3, 4 or 5 and the digits of L(k) are in nondecreasing order.at n=6A372151
