Abstract
We show that the image of the representation of the modular
group SL(2, Z) arising from the representation category Rep(D(G)) of the
Drinfeld double D(G) is isomorphic to the group PSL(2, Z/nZ) × S3, when
G is either the dihedral group of order 2n or the dihedral group of order 4n
for some odd integer n ≥ 3
