The group has 41 irreducible representations. β The S₈₀ point group could also be named C_80i, because the S₈₀ axis is identical to a roto-inversion axis of order 80. γ The S₈₀ point group is isomorphic to C₈₀. δ The S₈₀ point group is generated by one single symmetry element, S₈₀. Therefore, it is a cyclic group. ε The lowest nonvanishing multipole moment in S₈₀ is 4 (quadrupole moment). ζ This is an Abelian point group (the commutative law holds between all symmetry operations). The S₈₀ group is Abelian because it contains only one symmetry element, all the powers of which necessarily commute (sufficient condition). In Abelian groups, all symmetry operations form a class of their own, and all irreducible representations are one-dimensional. η Because the group is Abelian and the maximum order of rotation is >2, some irreducible representations have complex characters. These 78 cases have been combined into 39 two-dimensional representations that are no longer irreducible but have real-valued characters. Accordingly, 39 pairs of left and right rotations have been combined into one two-membered pseudo-class each. θ The 39 reducible “E” representations almost behave like true irreducible representations. Their norm, however, is twice the group order. Therefore, they have been marked with an asterisk in the table. This is essential when trying to decompose a reducible representation into “irreducible” ones using the familiar projection formula. ι Some of the characters in the table are irrational because the order of the principal axis is neither 1,2,3,4 nor 6. These irrational values can be expressed as cosine values, or as solutions of algebraic equations with a leading coefficient of 1. All characters are algebraic integers of a degree much less than half the order of the principal axis. κ The point group corresponds to a constructible polygon, as the order of the principal axis is a product of any number of different Fermat primes (3,5,17,257,65537) times an arbitrary power of two. Therefore, all characters have an algebraic degree which is a power of two and can be expressed as radicals involving only square roots and integer numbers.
