Sorry;just proved that 23 is a non-residue of 7919 upto infinite order. This was done with aid of my paper "Euler's generalization of Fermat's theorem ( a further generalization)- Hawaii international conference ,2004.
Verification : pari code -

Also is(n)=Mod(17,7919)^n==23

Last fiddled with by devarajkandadai on 2020-07-13 at 14:00 Reason: Corrected pari code
