Abstract: We investigate the existence of primes p>5 for which the residues of 2!, 3!, ..., (p-1)! modulo p are all distinct. We describe the connection between this problem and Kurepa’s left factorial function, and report that there are no such primes less than 10 11 .

Keywords: left factorial; factorial; prime numbers

Classification (MSC2000): 11B83; 11K31
