%N Records for the number of integers k such that an integer is of the form k + reverse(k).

%C RECORDS transform of A067032. A067035 gives the corresponding integers at which these records are attained.

%e 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).

%Y Cf. A067030, A067031, A067032, A067033, A067034, A067035.
