   en.wikipedia.org/wiki/List_of_Mersenne_primes...

   The following is a list of all currently known Mersenne primes and perfect numbers, along with their corresponding exponents p. As of 2024 [update] , there are 52 known Mersenne primes (and therefore perfect numbers), the largest 18 of which have been discovered by the distributed computing project Great Internet Mersenne Prime Search , or ...

3. Seventh power - Wikipedia

   en.wikipedia.org/wiki/Seventh_power

   In arithmetic and algebra, the seventh power of a number n is the result of multiplying seven instances of n together. So: n 7 = n × n × n × n × n × n × n.. Seventh powers are also formed by multiplying a number by its sixth power, the square of a number by its fifth power, or the cube of a number by its fourth power.

4. Exponentiation - Wikipedia

   en.wikipedia.org/wiki/Exponentiation

   This definition of exponentiation with negative exponents is the only one that allows extending the identity + = to negative exponents (consider the case =). The same definition applies to invertible elements in a multiplicative monoid , that is, an algebraic structure , with an associative multiplication and a multiplicative identity denoted 1 ...

5. Prime power - Wikipedia

   en.wikipedia.org/wiki/Prime_power

   Prime powers are powers of prime numbers. Every prime power (except powers of 2 greater than 4) has a primitive root; thus the multiplicative group of integers modulo p n (that is, the group of units of the ring Z/p n Z) is cyclic.

6. Tetration - Wikipedia

   en.wikipedia.org/wiki/Tetration

   There is no standard notation for tetration, though Knuth's up arrow notation and the left-exponent x b are common. Under the definition as repeated exponentiation, n a {\displaystyle {^{n}a}} means a a ⋅ ⋅ a {\displaystyle {a^{a^{\cdot ^{\cdot ^{a}}}}}} , where n copies of a are iterated via exponentiation, right-to-left, i.e. the ...
