Improper rotations correspond to orthogonal matrices with determinant − 1, and they do not form a group because the product of two improper rotations is a proper rotation.

For a given geometric figure in a given geometric space, consider the following equivalence relation: two automorphisms of space are equivalent if and only if the two images of the figure are the same ( here " the same " does not mean something like e. g. " the same up to translation and rotation ", but it means " exactly the same ").

For doing this equivalence, we will have to define how will we represent a rotation with this 4D-embedded surface.

When the extrinsic rotations equivalence is used the given angles are inverted respect the former, meaning that the first angle is the intrinsic rotation and the last one the precession.

No geometrical information is lost when using the rotation equivalence because the static parameters can be calculated from the name of the convention.

Using the equivalence between Euler angles and rotation composition, it is possible to change to and from matrix convention.
