Abstract
All bands groups of crystallographic and hyper-crystallographic $P$-simmetries are counted. Using these results it is shown that 6-dimensional Enclidian space 22548 simmetry groups of category $G_{6321}$ exist and in 7-dimensional space 300384 different symmetry groups of category $G_{76321}$ exist.
