I was thinking about the fact that when I do web research for "Alpha Phi Omega" that everything would come up (and more) if I were trying to do web research for Alpha Phi. I'm trying to think about which GLOs are subsets of others that are at least moderately known (strong regional at least)

Alpha Phi: Alpha Phi Alpha, Alpha Phi Omega, Alpha Phi Delta, Alpha Phi Gamma and probably a few more (not familiar with any 'something Alpha Phi' groups.)

Both Sigma Alpha Epsilon and Alpha Epsilon Pi: Sigma Alpha Epsilon Pi.
Phi Mu: Phi Mu Delta
Sigma Nu: Alpha Sigma Nu

Any others spring to mind?

*Note, I'm not counting if a letter is added in the middle, so as an example Beta Pi (if it existed) would not be a subset of Beta Theta Pi
