COMMENTS
Such a number will always have the maximum allowable digit in all places that are larger in base n than in factorial base. The remaining digits can be checked sequentially, since the difference between place values in factorial base and base n increase by more than a factor of n at that point. - Charlie Neder, Jun 12 2019

EXAMPLE
We have 2221 in base 3 is equal to 79 and in factorial base is equal to 65. There is no greater number in base 3 whose factorial base interpretation is less than the number itself. So a(3)=79.
