Conformal symmetries of a sphere are generated by the inversion in all of its hyperspheres. On the other hand, Riemannian isometries of a sphere are generated by inversions in geodesic hyperspheres (see the Cartan–Dieudonné theorem.) The Euclidean sphere can be mapped to the conformal sphere in a canonical manner, but not vice versa.

Indiana University of Pennsylvania, one of two the largest university of the Pennsylvania State System of Higher Education, first opened in 1875 as the Indiana Normal School. Upon opening, John Sutton Hall was the school's only building, housing dormitories for all 225 students. Sutton Hall additionally held classroom and office space, an ...
The sum of the angles of a spherical triangle is not equal to 180°. A sphere is a curved surface, but locally the laws of the flat (planar) Euclidean geometry are good approximations. In a small triangle on the face of the earth, the sum of the angles is only slightly more than 180 degrees. A sphere with a spherical triangle on it.
Independent regional campuses, such as Indiana University Kokomo, are included. Indiana has several universities that meet the definition of a flagship institution, with the most commonly cited being Indiana University Bloomington and Purdue University. The Indiana state code designates the Indiana University System as the university of the ...
