River Lune Lancaster district at times when the statutory services require assistance. The team is equipped with rescue sleds and a powered inflatable boat for use on the river. The RNLI can also be seen on the river fairly regularly, including both the D class and their Hovercraft, The Hurley Flyer. Rather than transit to scene from the Lifeboat station, the RNLI will often drive to the scene, often launching at Snatchems Golden Ball pub. River Lune The River Lune (archaically sometimes Loyne) is a river in length in Cumbria and Lancashire, England. The river begins as a stream at Newbiggin, in
Spherical lune the second half great circle has moved a full circle, and the lune in between covers the sphere as a spherical monogon — the area formula for the spherical lune gives 4π"R", the surface area of the sphere. A hosohedron is a tessellation of the sphere by lunes. A n-gonal regular hosohedron, {2,n} has "n" equal lunes of π/"n" radians. An "n"-hosohedron has dihedral symmetry D, ["n",2], (*22"n") of order 4"n". Each lune individually has cyclic symmetry "C", [2], (*22) of order 4. Each hosohedra can be divided by an equatorial bisector into two equal spherical triangles. The visibly lighted
