Integers n such that n = A067030(j) for some j and [largest integer k such that k is not of the form m + reverse(m) for any m (cf. A067031) and n occurs in the 'Reverse and Add' trajectory of k.] is smaller than [largest k such that n = k + reverse(k)]. - A067030(j) is a term iff A067034(j) is in A067030.

Examples

			4 = A067030(2) is in the sequence, since A067286(2) = 1 < 2 = A067034(2). 121 = A067030(21) is in the sequence, since A067286(21) = 92 < 110 = A067034(21).
