- Palindromes with exactly 7 prime factors (counted with multiplicity).at n=16A046333
- Golden rectangular box numbers: a(n) = n*A007067(n)*A007067(A007067(n)).at n=27A050510
- Palindromes sandwiched between twin primes.at n=15A113838
- Amicable triples: numbers such that sigma(x) = sigma(y) = sigma(z) = x+y+z, x<y<z. We order these triples according to the common value of sigma. Sequence gives z numbers.at n=15A125492
