WebJul 11, 2015 · The table for the group with set { f, t } and operation xor is: [ x o r f t f f t t t f] So we see there is a one-to-one correspondence between the groups. If we replace f with 0 and t with 1 and xor with +, then they become the same. For all groups it is required that the operation is associative, i.e. that ( a + b) + c = a + ( b + c) WebThe second property, that XOR by 1 inverts the value, is useful for flipping a set of bits. Generally, XOR is used for equality testing (a^b!=0 means a!=b), controlled bitwise inversion, and crypto.
