  It is experimentally known that achiral hyperbolic 3-manifolds are quite
sporadic at least among those with small volume, while we can find plenty of
them as amphicheiral knot complements in the 3-sphere. In this paper, we show
that there exist infinitely many achiral 1-cusped hyperbolic 3-manifolds not
homeomorphic to any amphicheiral null-homologous knot complement in any closed
achiral 3-manifold.
