Query: Practical bounds for a Dehn parental test   In their article "The shape of hyperbolic Dehn surgery space," Hodgson and
Kerckhoff proved a powerful theorem, half of which they used to make Thurston's
Dehn surgery theorem effective. The calculations derived here use both halves
of Hodgson and Kerckhoff's theorem to give bounds leading towards a practical
algorithm to tell, given two orientable hyperbolic 3-manifolds M, N of finite
volume, whether or not M is a Dehn filling of N.
