Name of three evenly spaced primes

What's the name of three evenly spaced primes (Like {3, 5, 7} or {3, 7, 11})?

Are there any theorems relating to them?

Those are three primes in arithmetic progression, a PAP-3.

There are a number of conjectures that would suggest that infinitely many triples of such primes.

Here's a page of records:
