also present similar algorithms for the normalisers of the other quasisimple classical groups. 1. Introduction. 1.1. Motivation. The spinor norm is.
Finding the spinor norm of an element using a proposition in 'The Maximal Subgroups of the Low-Dimensional Finite Classical Groups'.
The spinor norm is a homomorphism from to the multiplicative group modulo squares of: i.e., it is a homomorphism that sends any element in.
