Dummit and
Foote refer to it as the "
quasidihedral group"; we
adopt that name in this article. All give the same presentation...

Alperin showed that the
Sylow subgroup must be dihedral,
quasidihedral, wreathed, or a
Sylow 2-subgroup of U3(4). The
first case was done by...

cyclic groups is metacyclic.
These include the
dihedral groups and the
quasidihedral groups. The
dicyclic groups are metacyclic. (Note that a
dicyclic group...
