comment Orders of a symmetric group
I see. It is much clearer to me now! Likewise, the total number of elements of order 5 is $\frac{5 \times 4 \times 3 \times 2 \times 1}{5} = 24$, yes? Thank you for the help!

comment Finding all partial order relations on a set
Thanks for the source! It looks rather useful. I'll definitely remember it!

comment Finding all partial order relations on a set
The 3 element set is much clearer to me now. Thank you very much for the detailed answer! I tried finding all Hasse diagrams for the 4 element set, but I can only think of 12 types. (I drew them by hand, so it is difficult to display them on here.) Is there some list of diagrams I can compare mine to, to see which ones I missed?

comment Finding all partial order relations on a set
My bad, I just selected finite small sets off the top of my head. I suppose we could just then consider the 3 and 4 element sets? (Since I know the 0, 1, and 2 element sets are trivial.)
