Hi, I am looking for an extension of the built-in routine Factor to factorization with respect to quaternions. Factor has an option "GaussianIntegers->True" which allows, e.g. x^2+y^2 =>(x+I y)(x-I y). For expressions such x^2+y^2+z^2+t^2 (and similar constructs) factorization into the product of q=(x+I y+ J z + K t) and q^* (the conjugate quaternion) would be useful. Does anybody knows such an extension (or how it could be done) for the routine Factor? Thanks.
