 OFFSET 1,2 COMMENTS First differs from A179239 at n = 83; a(83) = 120 and A179239(83) = 122. This sequence is a supersequence of A179239. If there is a zero digit, then we do not consider the cyclic shift which begins with the zero digit. The number 0 should also be in this list. The initial digit of any term must be its smallest nonzero digit. - M. F. Hasler, Oct 18 2019 LINKS David A.
