Table of n, a(n) for n=1..10.


EXAMPLE

12 is in the sequence since the persistence of 12 is at most 1 in any base. I.e. it takes at most one step to go from 12 to a single digit in any base, e.g. in base 2 we have 1100 > 0. In base 5 we have 22 > 4. In bases 12 and above the initial number is already a single digit.
This sequence is complete  there are no other terms.  Alois P. Heinz, Jul 31 2014
