Saab 9-5 as undercover, in several parts of its native Sweden, alongside the Volvo V70. Several police forces in the UK also used the 9-5 in their fleets, mostly in Aero specification. The city of Aspen, Colorado, used Saabs as patrol cars from early 1970s until 2005, when the 9-5 was discontinued in favor of Volvo XC90. The town of Vail, Colorado likewise used Saabs from 1980 onwards, but in 2005, the black 9-5 patrol cars were replaced by Ford Explorers, due to budget reasons. In 2006, Lothian and Borders Police in Edinburgh, Scotland, began operating three Saab 9-5 Aero 2.3T patrol
9-orthoplex 9-orthoplex In geometry, a 9-orthoplex or 9-cross polytope, is a regular 9-polytope with 18 vertices, 144 edges, 672 triangle faces, 2016 tetrahedron cells, 4032 5-cells "4-faces", 5376 5-simplex "5-faces", 4608 6-simplex "6-faces", 2304 7-simplex "7-faces", and 512 8-simplex "8-faces". It has two constructed forms, the first being regular with Schläfli symbol {3,4}, and the second with alternately labeled (checkerboarded) facets, with Schläfli symbol {3,3} or Coxeter symbol 6. It is one of an infinite family of polytopes, called cross-polytopes or "orthoplexes". The dual polytope is the 9-hypercube or enneract. There are two Coxeter groups associated with the 9-orthoplex, one regular,
