%N n sets a new record for the number of integers k such that k is not of the form m + reverse(m) for any m and n occurs in the 'Reverse and Add' trajectory of k (cf. A067284).

%C A067288 gives the corresponding records.

%H <a href="/index/Res#RAA">Index entries for sequences related to Reverse and Add!</a>

%e 33 belongs to the sequence because three integers k (viz. 3, 21, 30) are not of the form j + reverse(j) for any j and 33 occurs in the "Reverse and Add!" trajectory of these k and for m < 33 there are at most two integers which have the corresponding property.

%Y Cf. A067030, A067031, A067032, A067035, A067036, A067284, A067288.
