Greeks whose names are subsets of others?
 

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

Alpha Chi Omega and Chi Omega

Took the words right out of my mouth!

The Alpha Chi Omega/Chi Omega thing made it so hard for me to search for gifts for my daughters online, even when I put Chi Omega in quotes!

There was a problem at the last college I taught at with this. There had been a Phi Mu Alpha Sinfonia chapter there forever and they called themselves Phi Mus, even though I've heard that most chapters call themselves Sinfonians. So when a Phi Mu chapter colonized, there were obviously problems!

Alpha Gamma Delta and Delta Gamma ... Searching for one always brings up results for the other!

Also, Alpha Delta Gamma

Amen!

In an advanced search (on some websites) you can search for:
Chi Omega -Alpha

Good! BlazerCheer wants some more Chi O flip-flops so I'll try that!

Sigma Alpha (Agriculture Sorority), Sigma Alpha Iota (Music), Alpha Sigma Alpha (NPC), and Alpha Sigma Phi (NIC)....

Did I miss any?

Well if you keep things in quotes, it will often put the ones in the right order first in Google, I think.

Alpha Sigma Phi doesn't fit the same pattern since the letters Alpha and Sigma are flipped from Sigma Alpha.

True - but Alpha Sigma Alpha, Alpha Sigma Tau, Alpha Sigma Phi, Alpha Sigma Multicultural Sorority, and Alpha Sigma Lambda are all "Alpha Sigma"

The first time I went through the PM process in Sinfonia, one of the other PMs called us Phi Mu once, at which point i shut him down and said to never say that again because it was the name of a sorority.

What about Kappa Alpha and Kappa Alpha Theta. Also Phi Sigma Kappa and Sigma Kappa. Finally, Phi Kappa Sigma and Kappa Sigma.

Gamma Phi Beta & Zeta Phi Beta (Also Gamma Beta Phi Honor Society). Also sometimes FIJI!
