Is the vector cross product only defined for 3D? Wikipedia formally introduces it as, for vectors $$\vec a$$ and $$\vec b$$,$\vec a\times \vec b=(||\vec a|| ||\vec b|| sin \Theta )\vec n$Where $$\vec n$$ is the unit normal vector. It also mentions that n is vector normal to the plane made by a and b, implying that a and b are 3D vectors. Wikipedia mentions something about a 7D cross product, but I'm not going to pretend I understand that. However, working off a definition I more or less invented (so I cannot tell how accurate it is), I can theorize a "cross product" that spans over any number
