WebThe third type involves unprimed elements of the subgroup H of index 2 of G (H is a so-called “halving subgroup” of G), and the remaining operators G\H (read G “not” H) that are being primed, from the construction M = H ∪ (G\H)1′. These resulting 58 magnetic groups are called “black-white” or Heesch groups. WebMade available by U.S. Department of Energy Office of Scientific and Technical Information ...
