• a(1) =7, a(n) = smallest multiple of a(n-1) (not equal to 10^k*a(n-1)) obtained by inserting digits anywhere in a(n-1).at n=3A080492
• a(1) = 7, a(n) = smallest palindromic multiple of a(n-1) obtained by inserting digits anywhere in a(n-1).at n=3A082782
• Palindromes formed from the concatenation of n, sum of n and R(n), and R(n) with its leading zeros; or 0 if no such palindrome exists. R(k) is the digit reversal of k.at n=16A084998
• Number of sequences of 5 throws of an n-sided die (with faces numbered 1, 2, ..., n) in which the sum of the throws first reaches or exceeds n on the 5th throw.at n=19A264750
• a(1) = 7, a(n) = smallest palindromic nontrivial multiple of a(n-1) containing all decimal digits of a(n-1).at n=3A342347
