    en.wikipedia.org/wiki/4-Digits

    4-Digits (abbreviation: 4-D) is a lottery in Germany, Singapore, and Malaysia. Individuals play by choosing any number from 0000 to 9999. Then, twenty-three winning numbers are drawn each time. If one of the numbers matches the one that the player has bought, a prize is won.

  3. Four-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Four-dimensional_space

    Four-dimensional space ( 4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.

    Finally, the first two results each appeared to establish 11 dimensions, the third result appeared to specify the theory, and the last result explained why the observed universe appears to be four-dimensional. Many of the details of the theory were fleshed out by Peter van Nieuwenhuizen, Sergio Ferrara and Daniel Z. Freedman.
