Idea
Given a symmetry group equipped with a homomorphism to an orthogonal group of some inner product space – for instance a Pin group – then its pseudovector representation is the linear representation (over the given ground field )
which is the tensor product of representations of the vector representation with the pseudoscalar representation (determinant-representation) :
