COMMENTS

Trajectory of n under map k -> A111273(k) is periodic with period length 2.

n = A111273(A111273(n)) and n <> A111273(n).

Apparently A111273 has infinitely many 2-cycles.

LINKS

Table of n, a(n) for n=1..47.

EXAMPLE

A111273(122) = 183 and A111273(183) = 122, hence 122 and 183 are in the

sequence.
