The derangement analogue of Kurepa's conjecture
The derangement analogue of Kurepa's conjecture
Let be a prime number. The relevant factorial sum is
Derangement factorial-sum conjecture. For every prime number ,
The claim is motivated by the preceding observation relating divisibility of the infinite factorial series to its truncation and is said to resemble Kurepa's conjecture. The paper gives computations below consistent with the claim, but no proof.
