Their spaces are darkened when drawing an Ulam spiral, which demonstrates that several quadratics with a leading coefficient of four generate several of these numbers.
These numbers are the subject of the bounded gap theorem proved by Tom Zhang in 2013. Their spaces are darkened when drawing an Ulam spiral, which demonstrates that several quadratics with a leading coefficient of four generate several of these numbers. Pairs of these numbers are added in Goldbach's conjecture, and pairs that differ by two are called twins. Unique products of these numbers are the basis of the fundamental theorem of arithmetic. Name these numbers left by the Sieve of Eratosthenes that are not composite, meaning that their only factors are one and themselves.
