13# Trigonal pyramid

3D ModelNoAI

Number of faces: 3

A crystal form is a group of faces, all of which have the same relation to the functions of symmetry on the crystal — the symmetry on a crystal has a direct influence on which specific forms are present.

There are 48 possible crystal forms (47 forms as defined by crystallographers of the Fedorov Institute, see https://skfb.ly/6VyCs) that can be developed as the result of the 32 combinations of symmetry.
