Trampoline skills can be written in FIG (Federation Internationale de Gymnastique) shorthand. FIG shorthand consists of one digit signifying the number of quarter rotations, followed by digits representing the number of half twists in each somersault, and a symbol representing the position of the skill. "/" represents a straight position, "<" represents a pike position, and "ο" represents a tuck position. For example, 42/ is a back somersault with a full twist in the straight position, 800ο is a double back somersault with no twists in the tuck position, and 821/ is a double somersault that has a full twist in the first full somersault and a half twist in the second full somersault while remaining in a straight position.
