Simultaneous Base Baffle (Posted on 2014-09-17) Difficulty: 3 of 5
Determine the smallest value of a positive integer N such that N is a palindrome in both base 3 and base 10. What is the next smallest value of N having this property?

*** N must have more than one digit in any base. So, trivial solutions like (4)base 10 or, (8)base 10 are not permissible.

Actually, 111 in base 3 is 11010.
