The triangular array whose right-hand diagonal sequence consists of Bell numbers. The Bell numbers can easily be calculated by creating the so-called Bell triangle, also called Aitken's array or the Peirce triangle after Alexander Aitken and Charles Sanders Peirce. [6] Start with the number one. Put this on a row by itself. (, =)

In mathematics, the Bell triangle is a triangle of numbers analogous to Pascal's triangle, whose values count partitions of a set in which a given element is the largest singleton. It is named for its close connection to the Bell numbers , [ 1 ] which may be found on both sides of the triangle, and which are in turn named after Eric Temple Bell .

If x is a triangular number, a is an odd square, and b = a − 1 / 8 , then ax + b is also a triangular number. Note that b will always be a triangular number, because 8 T n + 1 = (2 n + 1) 2 , which yields all the odd squares are revealed by multiplying a triangular number by 8 and adding 1, and the process for b given a is an odd ...
In the 5-bit Baudot codes, BEL is represented by the number 11 (0x0B) when in "figures" mode. [3] The code 0x2F is used in EBCDIC . In the programming language C (created in 1972), and in many languages influenced by it such as Python , the bell character can be placed in a string or character constant with \a . 'a' stands for "alert" or ...
