A new Garside structure for braid groups of type $(e,e,r)$
Résumé
We describe a new presentation for the complex reflection groups of type~$(e,e,r)$ and their braid groups. A diagram for this presentation is proposed. The presentation is a monoid presentation which is shown to give rise to a Garside structure. A detailed study of the combinatorics of this structure leads us to describe it as~\emph{post-classical}.
