Who's on the 4th base? (Posted on 2019-05-28) Difficulty: 3 of 5
21 is a palindrome in 4 distinct bases (bases: 2,4,6,20 ==> 10101,111,33,11,)

Find the smallest 3-digit number N such that both this number and its reversal are palindromes in at least 4 distinct bases.

Both number 1 and numbers higher than N do not qualify as bases.
Base 10 is in.
