A siteswap is a sequence encountered in Juggling in which each term is a Positive integer, encoded in Binary. The transition rule from one term to the next consists of changing some 0 to 1, subtracting 1, and then dividing by 2, with the constraint that the Division by two must be exact. Therefore, if a term is Even, the bit to be changed must be the units bit. In siteswaps, the number of 1-bits is a constant.
Each transition is characterized by the bit position of the toggled bit (denoted here by the numeral on top of the arrow). For example,
