So(5) (Paperback)

High Quality Content by WIKIPEDIA articles! In mathematics, SO(5), also denoted SO5(R) or SO(5, R), is the special orthogonal group of degree 5 over the field R of real numbers, i.e. (isomorphic to) the group of orthogonal 5x5 matrices of determinant 1. SO(5) is a subgroup of the direct Euclidean group E+(5), the group of direct isometries, i.e., isometries preserving orientation, of R5, consisting of elements which leave the origin fixed. More precisely, we have: SO(n) cong E+(5) / T where T is the translational group of R5.
