Hi
Below are some suggestions for this entry:
1) Consider this restructuring of the proof:
If a,b,c,d are elements in G, then
(a.b).(c.d) = a.(b.(c.d))
= a.(b.c).d
Thus,
(a.b).(b'.a') = a.(b.b').a'
= a.a' = e
and
(b'.a').(a.b) = b'.(a'.a).b
= b'.b
= e
here .= product, ' = inverse.
This is a matter of taste, but I think that this would make
the proof much easier to read.
2) Currently, the last equation should not end with a comma.
3) Consider renaming the entry to 'inverse of a product'
