We derive a necessary and sufficient condition for a symmetric family of sets to have a geometric representation involving a convex polygon and some of its diagonals. We show that cuts of value less than 6/5 times the edge-connectivity of a graph admit such a representation, thereby extending the cactus representation of all mincuts.
