I'm having trouble getting IsIrreducibleRingElement (and IsPrime) working
on SmallRing elements. For example:


Switching rings, elements, versions, and operating systems hasn't helped.

The built-in irreducibility tests are currently only available for the integers (and some rings of integers) and polynomial rings over fields. There is no method for the small rings, which is the reason for the error message you received.
