Comment (by kdilks):
It's my understanding that if repeated elements are allowed, then it's a
multichain, and if repeated elements aren't allowed then it's just a
chain. I don't know if Sage fully distinguishes between the two, so it
might be worth having a separate ticket just dedicated to making that
distinction clear in function names/documentation.
