```Hi, I found a sequence very similar to https://oeis.org/A178303.

Smallest multiple of 13 such that it is possible to form by concatenating
the first k positive integers in some order.

312,2314,14235,125346,1234675,12348765,123456879,12345791068,1234567891011,123456711812109,12345678910131112

(3, 1, 2)   312
(2, 3, 1, 4)   2314
(1, 4, 2, 3, 5)   14235
(1, 2, 5, 3, 4, 6)   125346
(1, 2, 3, 4, 6, 7, 5)   1234675
(1, 2, 3, 4, 8, 7, 6, 5)   12348765
(1, 2, 3, 4, 5, 6, 8, 7, 9)   123456879
(1, 2, 3, 4, 5, 7, 9, 10, 6, 8)   12345791068
(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11)   1234567891011
(1, 2, 3, 4, 5, 6, 7, 11, 8, 12, 10, 9)   123456711812109
(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 13, 11, 12)   12345678910131112

is it worth publishing or is it nonsense?
Best, Claudio
