Only you can say what this formula needs, or what you need from this formula.

You can see that there is the line "\begin{scope}[rotate=-40]" in the code. If you change -40 to 0 or remove "\begin{scope}" and "\end{scope}", the diagram will be horizontal, though the labels will overlap.

thanks,
If I change -40 to 0 or remove {scope} , then diagram will be bad form, because for example Z_n(H)Z_n(G)=Z_n(K) and Z_n(G) and HZ_n(G)=K are mixed!
my problem is this. I have my diagram has got a ratate=-40, and Z_n(H)Z_n(G)=Z_n(K) and Z_n(G) and HZ_n(G)=K are best form in diagram. now there are mixed to line.
excuse me, I can't write and speak english well.

Do you want just horizontal and vertical lines? Do you need the same labels, including $Z_n(H)Z_n(G)=Z_n(K)$? This label is too wide. You can move the points farther apart, or you can lift $Z_n(H)Z_n(G)=Z_n(K)$ more so that it does not overlap with $HZ_n(G)=K$. If you want to move the points farther, you can replace ++(2,0) with ++(4,0), for example.

It would be easier to rewrite the TikZ code. The current code is compact but difficult to understand and change.
