Summarize the following text delimited by triple backticks: """The NAME_1 jump or NAME_2 jump, named after its inventor, Norwegian figure skater NAME_2, is an edge jump performed 
in figure skating. It is the sport's oldest and most difficult jump, and the only basic jump in competition with a forward take-off, which makes 
it the easiest to identify. A double or triple NAME_1 is required in both the short program and the free skating segment for junior and senior 
single skaters in all events sanctioned by the International Skating Union (ISU).

The triple NAME_1 has become a common technical element in the men's singles discipline, while it is still rare among female single skaters. 
As of 2021, nineteen women have successfully completed the triple NAME_1 in competition. The quadruple NAME_1 was successfully executed in 
competition for the first time in 2022, but has not yet been landed by a female skater. Compared to other basic figure skating jumps, the 
NAME_1 requires an extra half revolution, which makes a triple NAME_1 "more a quadruple jump than a triple", according to figure skating expert 
NAME_3.""" Provide your reponse without using the word text.
