I actually think this is a good place to have them described.
<rev>^<number> is about specifying a single commit.  These two are
not that (you can say HEAD^2^@ but you cannot say HEAD^@^2, for
example).

These two are special cases I'm not too familiar with, particularly
the r1^! which I didn't understand from the description...

<rev>^@ is all parents of <rev>, that is

  <rev>^@  ==  <rev>^1 <rev>^2 ... <rev>^<n>

where <n> is number of parents commit <rev> has.


<rev>^! is (if standalone) a single commit range, only <rev> revision.
It is actually

  <rev>^!  ==  ( <rev> --not <rev>^@ )

that is, reachable from <rev> but not from any of its parents.
Parentheses here denote that `--not` does not affect the rest of
rev-like parameters.


Hope that helps
