Eight spherical gears of which four are turned at any time in conjunction. The very rare case of an abelian twistypuzzle.

Spherigear Loop is a loop of spherigears. This puzzle is using the mechanism of Spherigear Transmission, which Oskar invented half a year before this puzzle and for which he searched an application.
Each of the eight spherigears is connected to a little gear system with respectively 10, 20, 16, 12, 18, 15, 21, and 14 teeth. When the loop is pushed flat, four spherigears can turn independently of the other four. This way, the puzzle can be scrambled. The object is to unscramble the puzzle and to get each of the rings back to their starting state. Each pair of adjacent rings has a common factor. This is on purpose, to make the solving more difficult.
It is the rare example of a twisty puzzle making up an abelian group which means that the order of the moves does not matter.
