 OFFSET 1,1 COMMENTS Every integer that occurs in this sequence occurs at least twice. LINKS Table of n, a(n) for n=1..52. EXAMPLE The second odd non-binary-palindrome is 13, which is 1101 in binary. The smallest positive integer that, when written in binary, contains both 1101 and its reverse (1011) is 27, which is 11011 in binary. CROSSREFS Cf. A164861.
