OK, OK, I admit I'm a total dork, but Whitney's question at the end of my daily post thread was bothering me and I just HAD to figure it out.
So here is how I believe IHQ figures out the names:
Remember the original five provinces came about in this order:
1. Alpha: NorthEast
2. Beta: Upper MidWest
3. Gamma: SouthEast
4. Delta: West
5. Epsilon: Lower MidWest
Alpha went through the entire alphabet with Alpha Omega chartering in 1971. The Northeast chapters then jumped to Zeta, which is the 6th letter of the alphabet.
See what I mean? It goes in groups of 5! So here's how every single future chapter will be named:
The Northeast Province went from Alpha to Zeta. Once we charter Zeta Omega, the northeast chapters will go to Lambda. When they charter Lambda Omega, NE will go to Pi. From Pi it will go to Phi.
Upper Midwest Provence is still on Beta Tau. Once we charter Beta Omega the Upper Midwest will go to Eta, then Mu, then Rho, then Chi.
The Southeast Province went through Gamma, then it jumped to Theta. Once Theta Omega is chartered, SE chapters will jump to Nu, then Sigma, then Psi.
West Province has only gone to Delta Sigma (go OTW!), but once it charters Delta Omega, Western Chapters will go to Iota, then Xi, then Tau, then Omega.
Lower MidWest Province finished Epsilon, then moved to Kappa. After Kappa is finished, it would go to Omicron, and then Upsilon.
I know this sounds complicated, but if you write out the Greek alphabet and then place each province next to it, I promise the pattern will jump out at you immediately!
OK, I know I am totally sick and have WAY too much time on my hands.
