Noun1.parity bit - (computer science) a bit that is used in an error detection procedure in which a 0 or 1 is added to each group of bits so that it will have either an odd number of 1's or an even number of 1's; e.g., if the parity is odd then any group of bits that arrives with an even number of 1's must contain an error
computer science, computing - the branch of engineering science that studies (with the aid of computers) computable processes and structures
bit - a unit of measurement of information (from binary + digit); the amount of information in a system having two equiprobable states; "there are 8 bits in a byte"

We find J' + I is odd or, equivalently, even J' correspond with odd parity and vice versa.
To apply [Alpha] we follow the cycles of the notation: [Alpha] holds pcs 0, 2, 4, 6, 8, and t invariant, while pcs of odd parity are mapped successively: pc 1 is mapped to 3, 3 to 5, 5 to 7, 7 to 9, 9 to e, and e to 1.
