Multiple coincidences in dimensions d≤3

Ordinary coincidence site lattices (CSLs) are very well understood for a large class of lattices in dimensions d <= 4, as well as their generalization for various highly symmetric modules. Here, we consider multiple coincidence site lattices, i. e. intersections of several ordinary CSLs, which appear in connection with triple and multiple junctions. We restrict our considerations to the most prominent lattices in dimensions d <= 3 and present an outlook for further lattices and modules.
