well

I decided to make a list of frats that each sorority usually has socials, gamedays and other events with. But, sororities are constantly doing things/having socials with frats that are lower or higher in ranking.
Top
ZTA, ADPI, KD, AOPI, TriDelt, DG: Sigma Chi, SAE, ATO, Beta, Pike, Phi Delt

Theta, Piphi, DZ: KA, Theta Chi, ZBT, Delt and Kappa Sig

Deeph: they do things with literally everyone but tend to flock tep or ZBT

Chi O- does stuff with Delt and Kappa Sig and all the frats listed with AXO

AXO and Kappa: Tep, Aepi, Phi Tau and occasionally will do stuff with Delt and kappa sig

Phi mu and SK: Chi phi, lamda chi, pi lam, sigma nu

Aephi- pi lam and aepi
