This is off the National Panhellenic Conference website.

Early histories of women's fraternities contain accounts of "rushing and pledging agreements" or "compacts" among fraternities on various campuses, and also many stories of cooperation and mutual assistance. However, no actual Panhellenic organization existed and no uniform practices were observed. By 1902, it was obvious that some standards were needed, so Alpha Phi invited Pi Beta Phi, Kappa Alpha Theta, Kappa Kappa Gamma, Delta Gamma, Gamma Phi Beta, Delta Delta Delta, Alpha Chi Omega and Chi Omega to a conference in Chicago on May 24. Alpha Chi Omega and Chi Omega were unable to attend. The remaining seven groups met and the session resulted in the organization of the first interfraternity association and the first intergroup organization on college campuses. (National Interfraternity Conference for men's fraternities was organized in 1909, now called the North-American Interfraternity Conference).

The big 6 are 6 of those 7 initial attendees to the first conference.

Note, I am just expressing an opinion supporting certain groups as does everyone else.

So which of the 7 isn't a part of the Big 6?
