A is the highest point above the +X axis.Â B is where the +Y axis enters the bagel. C is the lowest point below the -X axis.Â D is where the -Y axis exits the bagel. These sharpie markings on the bagel ar

(sequence A000001 in the OEIS) For labeled groups, see OEIS:Â A034383. Each group is named by Small Groups library as Goi, where o is the order of the group, and i is the index used to label the group within that order.
