The presidents of the Atlantic 10 Conference have scheduled a meeting for Thursday with the intent of trying to solidify commitments from their membership, The Post has learned. According to a person with direct knowledge of the meeting, the A-10 is well aware league members Dayton, St. Louis, and Xavier, have "one foot out the door," to join the Group of Seven in a new conference.

Those three programs have poured millions of dollars into their programs in recent years for new facilities, increased budgets and higher coaches’ salaries.

Butler, which has done the same, including a renovation of venerable Hinkle Fieldhouse (where many of the famous scenes from the legendary movie "Hoosiers" were filmed), is another school on the Big East group’s wish list.

A Post source also said Creighton has been contacted by representatives of the seven Catholic schools that are leaving the Big East.

The Group of Seven is looking to add five teams to get to a 12-team league with Eastern and Western Divisions.

Creighton, located in Omaha, Neb., could join with Butler, Dayton, DePaul, Marquette, St. Louis and Xavier in a Western Division.

Duquesne also has emerged as a school of interest because it would get the Group of Seven back into Pittsburgh and it has upgraded its facilities with the opening of the Power Center in 2007.

St. Mary’s, from the San Francisco area, and Gonzaga, from Seattle, are also possibilities, but the Group of Seven would have to weigh the travel costs for non-revenue sports against the merits of the two highly respected men’s basketball programs.
