• Numbers k such that k | 10^k + 10.at n=22A015902
• a(n) = (n/2)*(n^4 + 1).at n=10A021003
• Numbers that are palindromic and divisible by 5.at n=23A043040
• Number of rooted trees with n nodes with every leaf at height 3.at n=27A048808
• Numbers k such that k^2 contains only digits {0,2,5}, not ending with zero.at n=11A058425
• a(n) = n*(n^2 + 1) if n is even, otherwise (n - 1/2)*(n^2 + 1).at n=37A071289
• Smallest n-digit palindromic multiple of n, or 0 if no such number exists.at n=4A083123
• 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=4A084013
• 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=4A084017
