Double factorial: if n is a positive integer, n!! is the product of all positive integers up to n with the same parity as n, and is read as "the double factorial of n". 3. Subfactorial : if n is a positive integer, ! n is the number of derangements of a set of n elements, and is read as "the subfactorial of n".
Since these are technically letters, they have their own Unicode code points in the Latin Extended-B range: U+01C0 for the single bar and U+01C1 for the double bar. Some Northwest and Northeast Caucasian languages written in the Cyrillic script have a vertical bar called palochka (Russian: палочка , lit. 'little stick'), indicating the ...

Some variants of X-bar notation use a double-bar (or double-prime) to represent phrasal-level units. X-bar theory derives its name from the overbar. One of the core proposals of the theory was the creation of an intermediate syntactic node between phrasal (XP) and unit (X) levels; rather than introduce a different label, the intermediate unit ...

In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
For example, (2,3) denotes the point with x-coordinate 2 and y-coordinate 3. The inner product of two vectors is commonly written as a , b {\displaystyle \langle a,b\rangle } , but the notation ( a , b ) is also used.
