Improved algorithms for left factorial residues
In [11], Alin Bostan together with Vladica Andrejić (University of Belgrade, Serbia) and Milos Tatarevic (CoinList, Alameda, CA) presented improved algorithms for computing the left factorial residues . They used these algorithms for the calculation of the residues , for all primes up to . Their results confirm that Kurepa’s left factorial conjecture is still an open problem, as they show that there are no odd primes such that divides . Additionally, they confirmed that there are no socialist primes with .
