    Dihedral group D5 - Symmetry of a Pentagon - Conjugacy classes

    Would (21345) be equivalent to permuting (12) and then rotating (12345)? As I can see that only certain permutations of S5 are within D5 but are you saying that (21345) would be an additional class for D5? As I have come to the conclusion that the extra class is the class of (13254), I think (ie...

    Which algebra vectors satisfy this (Trying to derive Schrödinger)

    It might just be me, but you have specified anything about your "K2" being a second derivative with respect to position. Also, what you are sort of writing is the time independent Schrodinger equation so having a time dependent potential function V is not correct.

    Dihedral group D5 - Symmetry of a Pentagon - Conjugacy classes

    Hi I am struggling to get my head fully around the conjugacy classes of D5. Everywhere I have looked seems to say that there are 4 irreducible representations of D5 which implies that there are 4 conjugacy classes. However, when examining the symmetry of the pentagon I am only able to see 3...
