High Quality Content by WIKIPEDIA articles! In basketball, a double is the accumulation of a double-digit number total in one of five statistical categories—points, rebounds, assists, steals, and blocked shots—in a game. Multiple players usually score double-digit points in any given basketball game; the double nomenclature is usually reserved for when a player has double-digit totals in more than one category. A double-double is the accumulation of a double-digit number total in two of the five categories in a game. The most common double-double combination is points-rebounds, followed by points-assists. Since the 1985–86 season, Karl Malone leads the National Basketball Association (NBA) in the points-rebounds combination with 811 and John Stockton leads the points-assists combination with 709. A triple-double is the accumulation of a double-digit number total in three of the five categories in a game. The most common way to notch triple-double is through points, rebounds, and assists. Oscar Robertson leads the all-time NBA list with 181. Jason Kidd leads the list among active players with 107. A quadruple-double is the accumulation of a double-digit number total in four of the five categories in a game. This has occurred four times in the NBA. A quintuple-double is the accumulation of a double-digit number total in all five categories in a game. One known quintuple-double has occurred at the U.S. high school level, when Tamika Catchings recorded one in 1997. A similar accomplishment is the five-by-five, which is the accumulation of at least five points, five rebounds, five assists, five steals, and five blocks in a game. In the NBA, only Hakeem Olajuwon and Andrei Kirilenko have accumulated multiple five-by-fives since the 1985–86 season.
