Using other radixes there are different automorphic numbers.

Base 30 is the first radix with three distinct prime factors and has 8 sequences of automorphic numbers.

The following digit sequence can be used to find the two k-digit automorphic numbers, where .

Base 6 is the first radix with non-trivial automorphic numbers and base 15 the first such odd radix.

In any given radix there are 2 sequences of automorphic numbers where p is the number of distinct prime factors in the radix.

Automorphic numbers are radix dependent, and the description above applies to automorphic numbers in base 10.
