Editing Pretzel link (section)

==Utility==
(−2,&nbsp;3,&nbsp;2<var>n</var>&nbsp;+&nbsp;1) pretzel links are especially useful in the study of [[3-manifold]]s.  Many results have been stated about the manifolds that result from [[Dehn surgery]] on the [[(−2,3,7) pretzel knot]] in particular.

The [[hyperbolic volume]] of the complement of the {{math|(−2,3,8)}} pretzel link is {{math|4}} times [[Catalan's constant]], approximately 3.66. This pretzel link complement is one of two two-cusped [[hyperbolic manifold]]s with the minimum possible volume, the other being the complement of the [[Whitehead link]].<ref>{{citation
