Abstract
We show that the braid group associated to the complex reflection group is an index subgroup of the braid group of the orbifold quotient of the complex numbers by a cyclic group of order . We also give a compatible presentation of and its braid group for each tagged triangulation of the disk with marked points on its boundary and an interior marked point (interpreted as a cone point of degree ) in such a way that the presentations of Brou\'{e}-Malle-Rouquier correspond to a special tagged triangulation.
