No idea, but UCF is currently the 2nd largest school in the nation by enrollment. 10 years ago, quota was hovering near 70, with chapter total at 110 (?), and the addition of sororities was extremely productive to bring the size of the huge pledge classes back down to the 50s. Which is still too high, IMHO. I am all for expansion, and I think the school could stand to add several more sororities over the next few years.
ETA: There are currently 10 sororities at UCF, if anyone cares.
