in order to correct a fautive "number", when it should have been
"residue", and also as to stand this in the sole investigation of
Euler's works, I reformulate my question:
***********
do we find, and where, in Euler 1) the notion of "minimum power"
(in French: "exposant minimal") and 2) the possibility of expressing
any residue by a power of a primitive root?
