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]

This category lists minerals that display the P4 3 32 (No. 212) space group symmetry of the hexagonal crystal system, or the enantiomorphic P4 1 32 (No. 213), depending on the chirality. Pages in category "Minerals in space group 212 or 213"
This category lists crystals that display the symmetry of the P3 1 21 space group (No. 152) of the trigonal crystal system, or the enantiomorphic space group P3 2 21 (No. 154). 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.
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.
