Appears in sequences

• Let b(n)=product of exponents of prime factorization of n. Sequence gives palindromes n such that b(n) is also palindromic and sets a new record.at n=8A085631
• a(n) is the smallest positive palindromic number whose binary expansion ends in exactly n zeros, or 0 if no such number exists.at n=11A302864
