Abstract
For any element a in a generalized 2n–dimensional Clifford algebra \({\fancyscript C}\)ℓ n (\({\Bbb F}\)) over an arbitrary field \({\Bbb F}\) of characteristic not equal to two, it is shown that there exits a universal invertible matrix P n over \({\fancyscript C}\)ℓ n (\({\Bbb F}\)) such that \( P^{{ - 1}}_{n} D_{a} P_{n} = \phi {\left( a \right)} \in F^{{2^{n} \times 2^{n} }} \), where ϕ(a) is a matrix representation of a over and D a is a diagonal matrix consisting of a or its conjugate.
