The 54 hemisymmorphic space groups contain only axial combination of symmetry elements from the corresponding point groups. ... 21: C222: C 2 2 2
Bridgeville, California (population 25) was the first town to be sold on eBay in 2002, and has been up for sale three times since. [1] In January 2003, Thatch Cay, the last privately held and undeveloped U.S. Virgin Island, was listed for auction by Idealight International. The minimum bid was US$3 million and the sale closed January 16, 2003. [2]
A space group is called symmorphic (or split) if there is a point such that all symmetries are the product of a symmetry fixing this point and a translation. Equivalently, a space group is symmorphic if it is a semidirect product of its point group with its translation subgroup. There are 73 symmorphic space groups, with exactly one in each ...

This category lists crystals that display the symmetry of the P6 2 21 space group (No. 180) of the hexagonal crystal system, or the enantiomorphic space group P6 4 21 (No. 181). The element or compound can assume either one of these two space groups. The crystal being referred to may be just one of the possible forms of a named element or compound.
