Abstract
A three-dimensional logical toy having regular, irregular or amorphous composite members of various shapes as symbol-bearing components and forming a unit, whereby the shaped members making up the composite body may be allocated to three main groups within which the configurations are identical, and whereby the shaped bodies may be rearranged by rotation along the axis traversing the geometrical central point of the composite body. The composite enclosing body (1) is made up of 18 shaped members (2, 3, 4) falling into three different groups and arranged in three mutually parallel layers, which are delimited by two surfaces, viz. one having the configuration of a regular hexagram and one parallel thereto having the configuration of a regular hexagonal. The body is shaped as a composite, form-locked enclosing body along the surface of hexagram configuration.
