All the national panhellenic groups please

[Sister Havana]

With DPhiE's colony this spring, Indiana now has 22 of the 26 NPC sororities.

Missing:
Alpha Sigma Tau
Phi Sigma Sigma
Sigma Kappa
Sigma Sigma Sigma

(There were also 22 sororities when I was there in the 90s. Sigma Kappa and Sigma Sigma Sigma both closed down in 1994, along with Alpha Sigma Alpha, which has since returned. Theta Phi Alpha and Delta Phi Epsilon weren't there at the time)

The only NPC groups that never had a chapter at IU are Alpha Sigma Tau and possibly Phi Sigma Sigma. (IU has a Greek walkway with stones listing every fraternity/sorority that has ever had a chapter at IUB. There is a stone for Phi Sigma Sigma with an establishment date of 1969, but I've never seen an IU chapter on a list of Phi Sigma Sigma chapters. Perhaps this was a colony that never fully chartered?)
