Spherical conformal geometry with geometric algebra

The recorded study of spheres dates back to the first century in the book Sphaerica of Menelaus. Spherical trigonometry was thoroughly developed in modern form by Euler in his 1782 paper [75]. Spherical geometry in n-dimensions was first studied by Schlafli in his 1852 treatise, which was published posthumously in [202]. The most important transformation in spherical geometry, the Mobius transformation, was considered by Mobius in his 1855 paper [171].
