Should this sequence include 0 (000  in any base)?

Numbers that are repdigits with length > 2 in some base.
(length > 2 because all numbers n > 2, are trivially represented as 11
in base n-1)

       7 = 111     base 2
      13 = 111     base 3
...

7, 13, 15, 21, 26, 31, 40, 42, 43, 57, 62, 63, 73, 80, 85, 86,
91, 93, 111, 114, 121, 124, 127, 129, 133, 146, 156, 157,
...
