It depends on whether you are referring to arbitrary bases or specific
ones. If you are describing any integer of 2 or greater, then
"general bases" or "arbitrary integer bases". If specific ones,
then "base 8" or "bases greater than 6" or whatever.

For numbers expressed in a particular base other
than binary, the word "radix" is sometimes used,
by saying e.g "... in radix-16 notation ...".
