COMMENTS
RECORDS transform of A067032. A067035 gives the corresponding integers at which these records are attained.
EXAMPLE
3 is a record since there is an integer n (viz. 33, cf. A067032) such that for three integers k we have n = k + reverse(k) and for m < n there are at most two integers j such that m = j + reverse(j).
