Mescaline the skills necessary to handle them safely. Special regulations restricting their availability, possession, storage or use may apply." The peyote cacti and other mescaline-containing plants such as San Pedro are illegal in Western Australia, Queensland, and the Northern Territory, whilst in other states such as Tasmania, Victoria and New South Wales, they are legal for ornamental and gardening purposes. In Canada, France, The Netherlands and Germany, mescaline in raw form and dried mescaline-containing cacti are considered an illegal drug. However, anyone may grow and use peyote, or "Lophophora williamsii", as well as "Echinopsis pachanoi" and "Echinopsis peruviana" without restriction, as
Compound of five tetrahedra orbit space "I"/"T" (of order 60/12 = 5) is naturally identified with the 5 tetrahedra – the coset "gT" corresponds to which tetrahedron "g" sends the chosen tetrahedron to. This compound is unusual, in that the dual figure is the enantiomorph of the original. If the faces are twisted to the right, then the vertices are twisted to the left. When we dualise, the faces dualise to right-twisted vertices and the vertices dualise to left-twisted faces, giving the chiral twin. Figures with this property are extremely rare. Compound of five tetrahedra The compound of five tetrahedra is one of the
