The terms "Ultra" and "Infra" themselves occur in prefix form when modifying Primes and Octaves, as well as when modifying Augmented and Diminished intervals, thus leading to the terms "Ultraprime", "Ultraoctave", "Infraoctave", "Infraaugmented", "Ultraaugmented", "Infradiminished" and "Ultradiminished"; however, the term "Infraprime" is not used since the perfect unison is already the smallest form of prime.  Note, for example, that while an Infraaugmented Fourth is the enharmonically equivalent to a Paramajor Fourth in 24edo, this is not the case in systems where the [[rastma]] is not tempered out.
