  2. Power of two - Wikipedia

    en.wikipedia.org/wiki/Power_of_two

    A prime number that is one less than a power of two is called a Mersenne prime. For example, the prime number 31 is a Mersenne prime because it is 1 less than 32 (2 5). Similarly, a prime number (like 257) that is one more than a positive power of two is called a Fermat prime—the exponent itself is a power of

    en.wikipedia.org/wiki/Universal_hashing

    The scheme assumes the number of bins is a power of two, =. Let w {\displaystyle w} be the number of bits in a machine word. Then the hash functions are parametrised over odd positive integers a < 2 w {\displaystyle a<2^{w}} (that fit in a word of w {\displaystyle w} bits).

  5. 1024 (number) - Wikipedia

    en.wikipedia.org/wiki/1024_(number)

    1024 is a power of two: 2 10 (2 to the tenth power). [1] It is the nearest power of two from decimal 1000 and senary 10000 6 (decimal 1296). It is the 64th quarter square. [2] [3] 1024 is the smallest number with exactly 11 divisors (but there are smaller numbers with more than 11 divisors; e.g., 60 has 12 divisors) (sequence A005179 in the OEIS).

    As one special case, it can be used to prove that if n is a positive integer then 4 divides () if and only if n is not a power of 2. It follows from Legendre's formula that the p -adic exponential function has radius of convergence p − 1 / ( p − 1 ) {\displaystyle p^{-1/(p-1)}} .

  8. Exponentiation - Wikipedia

    en.wikipedia.org/wiki/Exponentiation

    Powers of 2 appear in set theory, since a set with n members has a power set, the set of all of its subsets, which has 2 n members. Integer powers of 2 are important in computer science. The positive integer powers 2 n give the number of possible values for an n-bit integer binary number; for example, a byte may take 2 8 = 256 different values.
