It's quite effective at turning presentations of 3-manifold fundamental groups into actual 3-manifolds. I believe there is a rough description of what it does, by Googling-around and likely also in some Ian Agol posts, here on this forum. The strongest obstructions I suppose would be in terms of geometrization but you border on being kind of tautological if you go in that direction: free product decomp, amalgamated free product decomp, then there's a list of finite groups that arise, and a less compact list of infinite groups. . . | |
