%N Numbers of the form |m - R(m)| for m in A035137, where R(m) denotes the digit-reversal of m.
%C Created in an attempt to understand A035137. It would be nice to have an independent definition of these numbers. Obviously they are multiples of 9 - see A261909.
%e 21, 102, 1031 are some early terms in A035137, so this sequence contains 21-12=9, 201-102=99, 1301-1031=270.
%Y Cf. A002113, A035137, A261909.
