for NPC
U of Illinois has had a chapter of every current NPC except AST
Indiana U has had a chapter of every current NPC except AST and Phi Sigma Sigma
Syracuse U has had a chapter of every current NPC except Sigma Sigma Sigma
So a merger of AST and Tri-Sigma wouldn't have a conflict at those three schools, but I presume there is overlap at *some* school...
