512 (five hundred [and] twelve) is the natural number following 511 and preceding 513. In mathematics [ edit ] 512 is a power of two : 2 9 (2 to the 9th power) [1] and the cube of 8 : 8 3 .
The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3 . The cube is also the number multiplied by its square : n3 = n × n2 = n × n × n. The cube function is the function x ↦ x3 (often denoted y = x3) that maps a number to its cube. It is an odd function, as.
Cube root. In mathematics, a cube root of a number x is a number y such that y3 = x. All nonzero real numbers have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted , is 2, because 23 = 8, while the other ...
In mathematics [ edit] Visual proof that 33 + 43 + 53 = 63. 216 is the cube of 6, and the sum of three cubes: It is the smallest cube that can be represented as a sum of three positive cubes, [1] making it the first nontrivial example for Euler's sum of powers conjecture. It is, moreover, the smallest number that can be represented as a sum of ...
Dudeney number. In number theory, a Dudeney number in a given number base is a natural number equal to the perfect cube of another natural number such that the digit sum of the first natural number is equal to the second.
Mathematics: √ 3 ≈ 1.732 050 807 568 877 293, the ratio of the diagonal of a unit cube. Mathematics: the number system understood by most computers, the binary system, uses 2 digits: 0 and 1. Mathematics: √ 5 ≈ 2.236 067 9775, the correspondent to the diagonal of a rectangle whose side lengths are 1 and 2.
Rubik's family cubes of varying sizes. The original Rubik's cube was a mechanical 3×3×3 cube puzzle invented in 1974 by the Hungarian sculptor and professor of architecture Ernő Rubik. Extensions of the Rubik's cube have been around for a long time and come in both hardware and software forms. The major extension have been the availability ...
So CubeHash 8/1-512 is stronger (more secure) than CubeHash 1/1-512, and CubeHash 1/1-512 is stronger than CubeHash 1/2-512. The weakest possible version of this algorithm is CubeHash 1/128-h. However, there is a security versus time tradeoff. A more secure version will take longer to compute a hash value than a weakened version. References
