A 3D plane

If the plane is specified by the vector [a,b,c].
That is not true!
A plane is specified by [a,b,c,d].

Hello Dr Kempelmann,

Thank you for letting me know about this, I have corrected the following page:
http://www.euclideanspace.com/maths/geometry/elements/plane/

I think what I meant was 'plane orientation' rather than just 'plane' i.e. the set of planes that intersect the origin. It would be interesting to generalise this to any plane, I guess I would need to use 4x4 matrices to do this?

Thanks,

Martin
