2024 Nationals Pattern?

Quick question, I was told that the oil pattern we are bowling on in our bowling league, is the 2024 Nationals Pattern, and I can't seem to find a solid answer on what that pattern is. Pretty new to bowling so I'm not sure what is considered Nationals. I google it and I get the US open, but see multiple patterns, and different patterns for Teams and doubles and singles. Anyone have an idea on what I'm bowling on?
