Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
ABACABA is a "quickly growing word", often described as chiastic or "symmetrically organized around a central axis" (see: Chiastic structure and Χ). [4] The number of members in each iteration is a(n) = 2 n − 1, the Mersenne numbers (OEIS: A000225).
In combinatorial mathematics and theoretical computer science, a (classical) permutation pattern is a sub-permutation of a longer permutation.Any permutation may be written in one-line notation as a sequence of entries representing the result of applying the permutation to the sequence 123...; for instance the sequence 213 represents the permutation on three elements that swaps elements 1 and 2.

Several remarkable properties: [5] [6] It is the Fibonacci tile associated to the "diagonal variant" previously defined. It tiles the plane at any order. It tiles the plane by translation in two different ways. its perimeter at order n equals (+), where () is the n th Fibonacci number.
The X3.2.4 task group voted its approval for the change to ASCII at its May 1963 meeting. [18] Locating the lowercase letters in sticks [ a ] [ 15 ] 6 and 7 caused the characters to differ in bit pattern from the upper case by a single bit, which simplified case-insensitive character matching and the construction of keyboards and printers.
Restriction of a function: if f is a function, and S is a subset of its domain, then | is the function with S as a domain that equals f on S. 4. Conditional probability : P ( X ∣ E ) {\displaystyle P(X\mid E)} denotes the probability of X given that the event E occurs.
In modern browsers, the print function of the browser should automatically use the rules in the style sheets when you print an article, therefore the print command of your web browser is also useful. Certain page elements normally do not print; these include self references like section edit links, navigation boxes, message boxes and metadata. [1]
