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 2-hypercycle, each of which has a limiting circle on the ideal sphere. The Schläfli symbol of the "order-7-3 hexagonal honeycomb" is {6,7,3}, with three order-5 hexagonal tilings meeting at each edge. The vertex figure of this honeycomb is a heptagonal tiling, {7,3}. In the geometry of hyperbolic 3-space, the order-7-3 apeirogonal honeycomb (or ∞,7,3 honeycomb) a regular space-filling tessellation (or honeycomb). Each infinite cell consists of an order-7 apeirogonal tiling whose vertices lie on a 2-hypercycle, each of which has a limiting circle on the ideal sphere. The Schläfli symbol of the apeirogonal tiling honeycomb is {∞,7,3}, with three "order-7
