Abstract
For suitable finite groups G, we construct contractible 4-manifolds C with an effective G-action on whose associated pairs (C,g) for all are distinct smoothings of the pair . Indeed C embeds in a 4-manifold so that cutting out C and regluing using distinct elements of G yield distinct smooth 4-manifolds.
