About this deal

Gulf Air Flight GF2 connects London, United Kingdom to Bahrain, Bahrain, taking off from London Heathrow Airport LHR and landing at Bahrain International Airport BAH. GF(2) is the unique field with two elements with its additive and multiplicative identities respectively denoted 0 and 1.

All larger fields contain elements other than 0 and 1, and those elements cannot satisfy this property). Because of the algebraic properties above, many familiar and powerful tools of mathematics work in GF(2) just as well as other fields. F is countable and contains a single copy of each of the finite fields GF(2 n); the copy of GF(2 n) is contained in the copy of GF(2 m) if and only if n divides m. If your GF2 flight was cancelled or you arrived to Bahrain with a delay of 3 hours or more, you are entitled to 600€ in compensation, according to the EC 261/2004 regulation.Notations Z 2 and Z 2 {\displaystyle \mathbb {Z} _{2}} may be encountered although they can be confused with the notation of 2-adic integers. The elements of GF(2) may be identified with the two possible values of a bit and to the boolean values true and false. GF(2) (also denoted F 2 {\displaystyle \mathbb {F} _{2}} , Z/2 Z or Z / 2 Z {\displaystyle \mathbb {Z} /2\mathbb {Z} } ) is the finite field with two elements [1] (GF is the initialism of Galois field, another name for finite fields).

GF(2) can be identified with the field of the integers modulo 2, that is, the quotient ring of the ring of integers Z by the ideal 2 Z of all even numbers: GF(2) = Z/2 Z. In the latter case, x must have a multiplicative inverse, in which case dividing both sides by x gives x = 1.If the elements of GF(2) are seen as boolean values, then the addition is the same as that of the logical XOR operation. The flight departs London, Heathrow terminal «4» on January 29, 09:30 and arrives Manama/Al Muharraq, Bahrain on January 29, 19:10. The bitwise AND is another operation on this vector space, which makes it a Boolean algebra, a structure that underlies all computer science. When n is itself a power of two, the multiplication operation can be nim-multiplication; alternatively, for any n, one can use multiplication of polynomials over GF(2) modulo a irreducible polynomial (as for instance for the field GF(2 8) in the description of the Advanced Encryption Standard cipher).
