TheK-admissibility of 2A 6 and 2A 7
LetK be a field and letG be a finite group.G isK-admissible if there exists a Galois extensionL ofK withG=Gal(L/K) such thatL is a maximal subfield of a centralK-division algebra. This paper contains a characterization of those number fields which areQ 16-admissible. This is the same class of number fields which are 2A 6=SL(2, 9) and 2A 7 admissible.
