Vandiver proved in 1940 that Fermat's Last Theorem (x p + y p = z p) has no solution for integers x, y, z with gcd(xyz, p) = 1 if p is Euler-regular. Gut proved that x 2p + y 2p = z 2p has no solution if p has an E-irregularity index less than 5. [11] It was proven that there is an infinity of E-irregular primes.
The original, called Mersenne's conjecture, was a statement by Marin Mersenne in his Cogitata Physico-Mathematica (1644; see e.g. Dickson 1919) that the numbers were prime for n = 2, 3, 5, 7, 13, 17, 19, 31, 67, 127 and 257 (sequence A109461 in the OEIS), and were composite for all other positive integers n ≤ 257.

There are no known cases of naturally occurring mammalian parthenogenesis in the wild. Parthenogenetic progeny of mammals would have two X chromosomes, and would therefore be genetically female. [citation needed] In 1936, Gregory Goodwin Pincus inducing parthenogenesis in a rabbit. [67]
Epsilon Sculptoris (ε Scl, ε Sculptoris) is a binary star [12] in the constellation Sculptor.It is approximately 91.7 light years from Earth. [1]The primary component, Epsilon Sculptoris A, is a yellow-white F-type main-sequence star [3] with an apparent magnitude of +5.29. [2]

Boomerang attack. In cryptography, the boomerang attack is a method for the cryptanalysis of block ciphers based on differential cryptanalysis.The attack was published in 1999 by David Wagner, who used it to break the COCONUT98 cipher.
