Presentations of the braid group of the complex reflection group $G (d, d, n)$

Francesca Fedele, Bethany Rose Marsh

We show that the braid group associated to the complex reflection group $G (d, d, n)$ is an index $d$ subgroup of the braid group of the orbifold quotient of the complex numbers by a…
