In particular, we derive the coincidence index $Σ$ and calculate the number of different CSLs as well as the number of inequivalent CSLs for a given $Σ$. The hypercubic face centered case is dealt with in detail and it is sketched how to derive the corresponding results for the primitive hypercubic lattice.13 pages, 8 tablesMetric Geometry52C07, 05A15, 20F55, 20G45, 51F15, 20H15, 05A15text
