I want to ask:

When is the dihedral group $D_n$ admissible? Or, when does the Latin square of the Cayley table of a dihedral group have a transversal?

You should at least provide a reference where the specific meaning of the word 'admissible' you have in mind is explained: it has way too may meanings! Also, making sure the spelling in your question is correct will help attracting good answers. – Mariano Suárez-Alvarez Jul 26 '10 at 7:58
I've edited the question to make it readable, but I second Mariano's wish that the OP should define the notion of admissible. – José Figueroa-O'Farrill Jul 26 '10 at 14:01
It'd also be good for the OP to provide some motivation for how this question came up and why it's interesting. As it stands it looks like possible homework to me. – Noah Snyder Jul 26 '10 at 14:27
Looks like OP is talking about this: – Sonia Balagopalan Jul 26 '10 at 14:36

By theorems 5 and 6 of this paper, the answer is yes when n is even and no when n is odd.
