OEIS Sequences

Palindromes with exactly 3 distinct palindromic prime factors. A46409

a(n) = n⁴ + 2·n³ + 4·n² + 3·n + 1 = ((n+1)⁵+n⁵) / (2·n+1). A72025

Palindromes of form n² + 3·n + 1. A28349

Palindromes with exactly 3 palindromic prime factors (counted with multiplicity). A46377

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. A84998

Sphenic numbers k = p·q*r such that reversal(k) is also a sphenic number and reversal(k) = reversal(p)*reversal(q)*reversal(r). A242726

Composite palindromes whose divisors > 1 are all nontrivial palindromes (i.e., palindromes with at least two digits). A329100
