Comment (by darij):
+1 for splitting 1&2 | 3&4. This is particularly helpful to me, as I am
fairly sure I can review 1&2, but probably not 3&4 these days.
Johan Bosman's approach looks correct (mathematically -- haven't checked
the programming). It isn't even necessary to check that the two identities
are equal, since their existence already yields their equality.
