Why the "but"? My penultimate message, which began this thread,
said that both sets and masses could be sequences -- i.e. could
be ordered. (Maybe you're trying to address a different question,
the meaning of the Lojban technical/glossing term 'sequence'?)

As it happens, though, I'm not sure that sequential sets have
properties derived from their members. To my mind that is the
basic distinction between sets and groups/teams.
