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
Order-7-3 triangular honeycomb order-7-5 pentagonal honeycomb (or 5,7,5 honeycomb) a regular space-filling tessellation (or honeycomb) with Schläfli symbol {5,7,5}. All vertices are ultra-ideal (existing beyond the ideal boundary) with five order-7 pentagonal tilings existing around each edge and with an order-5 heptagonal tiling vertex figure. In the geometry of hyperbolic 3-space, the order-7-6 hexagonal honeycomb (or 6,7,6 honeycomb) is a regular space-filling tessellation (or honeycomb) with Schläfli symbol {6,7,6}. It has six order-7 hexagonal tilings, {6,7}, around each edge. All vertices are ultra-ideal (existing beyond the ideal boundary) with infinitely many hexagonal tilings existing around each vertex in an order-6 heptagonal tiling vertex
