- Smallest n-digit palindromic multiple of n, or 0 if no such number exists.at n=7A083123
- Smallest n-digit palindromic multiple of n. For n = 10k it is sufficient that the multiple is palindromic with leading zeros ignored. 0 if no such number exists.at n=7A084013
- Smallest n-digit palindromic multiple of n with a digit sum that is also a multiple of n. For n = 10k it is sufficient that the multiple is palindromic with leading zeros ignored. 0 if no such number exists.at n=7A084017
- Triangle read by rows in which row n gives n smallest n-digit multiples of n that are palindromes.at n=28A084024
