PreprintA small infinitely-ended 2-knot groupR.Budney and J.A.HillmanAbstractWe show that a 2-knot group discovered in the course of a census of 4-manifolds with small triangulations is an HNN extension with finite base and proper associated subgroups, and has the smallest base among such knot groups. Keywords: end; 2-knot; 4-manifold; virtually free.AMS Subject Classification: Primary 57Q45.
