Comments
This is a revision of an already published version of this paper. I would like to thank Susan Montgomery for pointing out a severe mistake in referring to a survey article by M.Cohen from 1985 and not to the paper by M.Cohen and D.Fishman from 1986 where the central problem of this paper had been originally addressed. I also would like to thank her for the reference of the Kac-Paljutkin paper
