(Which I don't thin it does.) I'm not trying to annoy - this is really a
very minor point at this point, though should be resolved. Anyway,
everything else seems quite fine - currently running tests.

discrepancies in sorting do not happen on a single system: the differences
are between two different systems so the way things are sorted on any
given Sage session will be the same, right?

equal if the names are the same, so that e.g. suitors can be added in a
different order, but you would only have the games be the same if the
names and preferences for that name corresponded, not if the games are
''isomorphic''. Am I right?
Yeah that's correct (if I'm understanding correctly): the equality is
based only on the names (which is because of the underling `sort`
methods that the players now have).
