COMMENTS
Primitive terms in A004086.
Corresponds with A023804 for 1 <= n <= 73. The term 81 in this sequence is "100" in base 9, in which 2 digits are the same, therefore 81 does not appear in A023804.
0 plus integers that are not a multiple of 10. - Chai Wah Wu, Mar 25 2021
Differs "in substance" from A209931, because e.g. this sequence contains 214 and 214 is not in A209931 (because 107|214 and 107 contains a zero). - R. J. Mathar, Jul 29 2021
Differs from the finite sequence A023804. - R. J. Mathar, Jul 07 2023
