How do i show that a group of symmetries of a regular quindecagon has order |G| = 30 ? And how do i describe the elements of G and classify them by their order? Thanks

Just a simple quickie, why are stars classified using the letters O, B, A, F, G, K and M? Is there any significance in the letters?
