Sorry, I didn't notice the typo. Indeed it was a nonempty intersection, and I've corrected the post.

comment Constructing a 3-regular graph with no 3-cycles
No, there cannot, but I'm having trouble writing this "formally". Do I simply write that this is because $k+1$, say, would only have edges between $k$, $k+2$, and $k+(n+1)$, and so $k+n$ is not included?

comment Finding the order of elements in a group?
Alright, so I picked up where you left off, and I found the following. $[4]^2 = [16]$, so $n = 2$ does not work. However, $[4]^{11} = [1]$, so $n = 11$ and since $11$ is least, then the order of $[4]$ is 11. Am I correct?
