Dear Madam/Sir

I   suspect a bug in Libre Office (Windows 10)       26.2.5.2 (x86_64)
gerrit.libreoffice.org / core / cd7284b4cbbfeb507e630c1aac019f4157393acb^! / .



I tried to evaluate  powers of  the group of integers modulo 23.
ie  $x^i $  mod 23, there are supposed to be non zero all of them.

I used the  formula:
=MOD($A8^V$2;23)
I CANOT  SEND YOU A SCREEN SHOT FROM THIS PLATFORM

I also used    an alternative  simpler  less  intensive (easier)  way 
 using the formula   MOD(Q5*$A5;23)  (previous    cell ttimes    first row 
moid 23  and the results are correct. 

screen shots from 2nd  mathod  follow
