A note on Deaconescu’s conjecture

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science
Hasanalizade [5] studied Deaconescu’s conjecture for positive composite integer n. A positive composite integer n ≥ 4 is said to be a Deaconescu number if S2(n) | ϕ(n) − 1.
