Thanks, just got confirmation that there is a mistake on the solution sheet.

Ok. I guess the wrong answer is on the teacher's solution sheet. Thanks :)

Why does it work for 2 and 7 too ?

comment How many numbers exists that are smaller than $p$ and prime with $p$?
Thanks, in short $3947$ is the answer I was looking for. Euler's totient function clarified my confusion.

Yeah, any power of 3 greater than will make the remainder 0.
