Abstract
The present invention is directed to a spacial logical toy having a total of twenty-six toy elements mounted on a spherical internal connecting element. The toy elements are assembled to a spacial body having an octagon cross section on any of the three mutually perpendicular axes. The surfaces of the twenty-six toy elements that make up the geometric solid are provided with one of three colors and are sequentially numbered (1-26) or lettered (A-Z) to provide each surface with a unique designation. The twenty-six toy elements are mixed by rotation of any adjacent nine elements relative to the remainder of the geometric solid. The objective or solution is to return the toy elements to an original sequential orientation.
