> Description :

    "True so far"-sequence. Last digit of a(n) must be seen
    as a glyph and preceding digits as a quantity. So "10"
    reads [one "0"] and "12" [one "2"] -- which are both true
    statements: there is only one "0" glyph so far in the
    sequence when [10] is read, and there is only one "2"
    glyph when [12] is read. The sequence is built with
    [a(n+1)-a(n)] being minimal and a(n+1) always "true so
    far". This explains why integers [11], [21], [22], [31],
    etc. are not in: their statements are false.

    The nice substring ...1112,1113,1114,1115,1116,1117...
    appears in the sequence -- which means that so far the
    whole sequence has used 111 "2", 111 "3", 111 "4", 111 "5",
    111 "6" and 111 "7"...

Note from David Wilson :

 

At a(2024) = 8945, the largest digit count is 894 5's. There are no more elements up to 8950. At 8950 and beyond, the "count" part of the number exceeds 894, and so cannot be in the sequence. Ergo the sequence is finite, with largest element a(2024) = 8945.

This sequence is now A102357
