On the intervals for the non-existence of covering systems with distinct moduli

Number Theory 2025-06-16 v1

Abstract

In a research seminar in 20062006, M. Filaseta, O. Trifonov, and G. Yu showed for each integer n3n\geq3 there is no distinct covering with all moduli in the interval [n,6n][n, 6n]. In 20222022, this interval was subsequently improved to [n,8n][n, 8n] by the first author and O. Trifonov. The first author then improved this bound to [n,9n][n, 9n] in 20232023. Building off their method, we show that for each integer n3n\geq 3, there does not exist a distinct covering system with all moduli in the interval [n,10n][n, 10n].
