	OFFSET	`1,2`
	COMMENT	`Intersection of A002113 and A067031. Every palindrome with an even number of digits is of the form k + reverse(k), for example 123321 = 123000 + 000321, so the sequence has no terms with an even number of digits.`
	EXAMPLE	`9 belongs to this sequence, since there is no k such that k + reverse(k) = 9 (cf. A067031).`
	CROSSREFS	`Cf. A002113, A067031, A068062.` `Sequence in context: A132286 A070788 A030148 this_sequence A062887 A062886 A133452` `Adjacent sequences: A068058 A068059 A068060 this_sequence A068062 A068063 A068064`
	KEYWORD	`base,easy,nonn`
