24 (twenty-four) is the natural number following 23 and preceding 25.
It is equal to two dozen and one sixth of a gross.
The many ways 24 can be constructed inspired a children's mathematical game involving the use of any of the four standard operations on four numbers on a card to get 24 (see 24 Game).
24 is also part of the only nontrivial solution pair to the cannonball problem,[1] and the kissing number in 4-dimensional space.
