Fibonacci prime
A Fibonacci prime is a Fibonacci number that is prime, a type of integer sequence prime.The first Fibonacci primes are (sequence A005478 in OEIS):
It is not known whether there are infinitely many...
Pisano period
In number theory, the nth Pisano period, written π(n), is the period with which the sequence of Fibonacci numbers, modulo n repeats. For example, the Fibonacci numbers modulo 3 are 0, 1, 1, 2, 0, 2, ...
Fibonacci numbers in popular culture
The Fibonacci numbers are a sequence of integers, starting with 0, 1 and continuing 1, 2, 3, 5, 8, 13, ..., each new number being the sum of the previous two. The Fibonacci numbers, and in conjunction...

Generalizations of Fibonacci numbers
In mathematics, the Fibonacci numbers form a sequence defined recursively by:That is, after two starting values, each number is the sum of the two preceding numbers.The Fibonacci sequence has been stu...
Golden ratio
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. The figure on the right illustrates the geometric relat...

Random Fibonacci sequence
In mathematics, the random Fibonacci sequence is a stochastic analogue of the Fibonacci sequence defined by the recurrence relation fn = fn−1 ± fn−2, where the signs + or − are chosen at random with e...
Lucas pseudoprime
Lucas pseudoprimes and Fibonacci pseudoprimes are composite integers that pass certain tests which all primes and very few composite numbers pass: in this case, criteria relative to some Lucas sequenc...

List of works designed with the golden ratio
Many works of art are believed to have been designed using the golden ratio, an irrational number that is approximately 1.618; it is often denoted by the Greek letter φ (phi).
It is claimed that S...
