===Applications=== Permutations are used in the [[interleaver]] component of the [[error detection and correction]] algorithms, such as [[turbo codes]], for example [[3GPP Long Term Evolution]] mobile telecommunication standard uses these ideas (see 3GPP technical specification 36.212<ref>{{cite web| url = http://www.3gpp.org/ftp/Specs/html-info/36212.htm| title = 3GPP TS 36.212}}</ref>). Such applications raise the question of fast generation of permutations satisfying certain desirable properties. One of the methods is based on the [[permutation polynomials]]. Also as a base for optimal hashing in Unique Permutation Hashing.<ref>{{cite journal |first1=Shlomi |last1=Dolev |first2=Limor |last2=Lahiani |first3=Yinnon |last3=Haviv |title=Unique permutation hashing |journal=Theoretical Computer Science |volume=475 |year=2013 |pages=59β65 |doi=10.1016/j.tcs.2012.12.047 |doi-access=free }}</ref>
