OK - well, your answer makes sense - that's what I would expect. I found a couple of mistakes in my notesâ€¦ perhaps I left out the 1. In another spot I had inserted a comma between (13)(12) when we were left multiplyingâ€¦so, no more texting during class for me?

Actually, $(13)(1)=(13)$ and definitely isn't equal to $(3)$. Did one of us (maybe me) say or write otherwise?

I actually can do most cycle products accurately, however, why does (13)(1) = (3) in $S_3$? If (13) is the reflection through the vertex 2, with 1 at the top of the triangle and numbering clockwise, I guess nothing happens when (13) is multiplied by the identity, (1). So 3 remains at the top, 2 is at 2 and 1 remains at 3 after the reflection through 2… right? So (13) is called (3)?
