When does $C(a^i)=C(a^j)$ if $|a|$ is finite?

$begingroup$


I am looking for a necessary and sufficient condition for $C(a^i)=C(a^j)$ to hold in a general group G given that $|a|$ is finite and known.



What if $|a|$ is a prime?



Here $C(a)={gin G ;| ;gag^{-1}=a}$

    Do you want it to hold for all $i,j$ or are you asking for a condition depending on $i,j$ that would imply $C(a^i)=C(a^j)$ for that particular $i,j$?
