This gear set includes many large non-circular gears as well as some small prime number gears.
The four biggest gears are:
180 (square), 180 (triangle), 160 (octagon), 160 (square). Each of these has a medium sized non-circular gear cutout.
This gear set is ideal if you want to use more large non-circular gears and ring. It pairs well with the Compact gear set or the Full Page gear set; either of which will provide lots of gears to roll around in the non-circular cutouts. To use the non-circular gears in a ring you'll want and enormous gear set; like the Enormous Hoops gear set, for example. For more details on why that is the case you can check out this explanation.
