There are also two sets of three C2

There are also two sets of three C2 axes in the plane of the snowflake, one set
through opposite points and one through the cut-in regions between the points. One of
each of these axes is shown in Figure 4-2. In molecules with more than one rotation axis,
the C, axis having the largest value of n is the highest order rotation axis or principal
axis. The highest order rotation axis for a snowflake is the C6 axis. (In assigning Cartesian
coordinates, the highest order C, axis is usually chosen as the z axis.) When necessary,
the C2 axes perpendicular to the principal axis are designated with primes; a single
prime (C2') indicates that the axis passes through several atoms of the molecule, whereas
a double prime (C2") indicates that it passes between the outer atoms.
