Index Entry

There are only three superficial axes of symmetry of crystallography. They are:

Spin of vertex )

Spin of mid-edge ) =three superficial axes

Spin of center of area )

(that is, c.g. of mid-faces) )

These are all the superficial surface angles which are the gravity. The central angles are the radiation.
