Webalgorithm (string): either farey (default) or todd-coxeter. If algorithm is set to "farey", then the generators will be calculated using Farey symbols, which will always return a minimal generating set. See farey_symbol for more information. If algorithm is set to "todd-coxeter", a simpler algorithm based on Todd-Coxeter enumeration will be used.

The Farey sequence for any positive integer is the set of irreducible rational numbers with and arranged in increasing order. The first few are. (OEIS A006842 and A006843 ). Except for , each has an odd number of terms and the middle term is always 1/2. Let , , and be three successive terms in a Farey series. WebNote: If you pass a double as it is, Fraction.js will perform a number analysis based on Farey Sequences. If you concern performance, cache Fraction.js objects and pass arrays/objects. The method is really precise, but too large exact numbers, like 1234567.9991829 will result in a wrong approximation. gamer lights for room
