Twin primes

Definition

Twin primes are pairs of prime numbers that have a difference of two, such as (3, 5) or (11, 13). They are an intriguing area of study in number theory and have connections to various unsolved problems in mathematics, including the famous Twin Prime Conjecture, which posits that there are infinitely many such pairs. The exploration of twin primes touches on fundamental concepts in extremal combinatorics and their applications in understanding prime distributions.
