Find the cosets of $D_{2n}$ in $S_n$
I tried to take examples and see, I did it in the case when $n=4$, but for the case $n=6$, the computation is became huge.
Is there a simple way in which I can see the problem?

I used Python to get the $60$ (left) cosets in $S_6$; the first defined function was copied from here (I can be blamed for the remaining code).
