WebIt turns out that the cross product is the k=2, n=3 special case of some math thing called the exterior product. The exterior product generalizes all previous notions: the cross product, the mixed product, the determinant, and more. This overall approach also unifies the k=1,2,3 cases in 3d and in any number of dimensions. WebDefinition.
