Although M. L. Frankenheim was the first to attempt to enumerate them, he miscounted and came up with one too many of them, a problem corrected by their namesake. They are translation subsets of Fedorov groups and each one is given a Pearson symbol. The primitive one has ten Wyckoff points belonging to two separate tetrahedrally coordinated sets. Of the cubic-derived ones, one is triclinic, two are monoclinic, and four are orthorhombic including the simple, base-centered, body-centered, and face-centered. In all totaling 14 basic unit cells in three dimensions, FTP, identify this set of crystal lattices named after a Frenchman.
