q divides 3 (q−1)/2 − 1; If p is a Sophie Germain prime greater than 3, then p must be congruent to 2 mod 3. For, if not, it would be congruent to 1 mod 3 and 2p + 1 would be congruent to 3 mod 3, impossible for a prime number. [15]
The latest Mods 2 and 3 feature stabilization and remote control ability. [6] All variants of the Mk 38 require two crewmembers for conducting maintenance (e.g., replacing the Bushmaster in the event it malfunctions, which takes five minutes).
by Wolstenholme's theorem satisfied by all prime numbers greater than 3 ( 2 p − 1 p − 1 ) ≡ 1 ( mod p 4 ) , {\displaystyle {2p-1 \choose p-1}\equiv 1{\pmod {p^{4}}},} solutions are called Wolstenholme primes (smallest example: 16843)
[1] [2] The SOPMOD kit is composed mostly of non-developmental items and commercial off-the-shelf (NDI/COTS) accessories packaged together to support four M4A1 carbines. [ 1 ] [ 3 ] It allows for the attachment of any Picatinny compatible accessory that fits the length of the weapon.
The only solutions up to 10 10 to the equation τ(p) ≡ 0 (mod p) are 2, 3, 5, 7, 2411, and 7 758 337 633 (sequence A007659 in the OEIS). [ 11 ] Lehmer (1947) conjectured that τ ( n ) ≠ 0 for all n , an assertion sometimes known as Lehmer's conjecture.

There are several types of secret sharing schemes. The most basic types are the so-called threshold schemes, where only the cardinality of the set of shares matters. In other words, given a secret S, and n shares, any set of t shares is a set with the smallest cardinality from which the secret can be recovered, in the sense that any set of t − 1 shares is not enough to give S.
If p is an odd prime and p − 1 = 2 s d with s > 0 and d odd > 0, then for every a coprime to p, either a d ≡ 1 (mod p) or there exists r such that 0 ≤ r < s and a 2 r d ≡ −1 (mod p). This result may be deduced from Fermat's little theorem by the fact that, if p is an odd prime, then the integers modulo p form a finite field , in which ...
