Comments

This is not the sequence A260255 although more than the first 111 terms are equal.

Examples

			21 is not in the sequence because 11 (the closest palindromic integer < 21) is not reachable by subtracting an integer < 10 from 21. The integers 32, 43 or 2018 are not in the sequence for the same reason.
