Example

From Antti Karttunen, Dec 26 2018: (Start)
The first twelve odd numbers and their base-6 representations (A007092) are:
    1    1
    3    3
    5    5
    7   11
    9   13
   11   15
   13   21
   15   23
   17   25
   19   31
   21   33
   23   35
thus the sequence begins with terms 1, 3, 5, 1, 1, 1, 3, 1, 5, 2, 1, 2, 3, 2, 5, 3, 1, 3, 3, 3, 5.
