Comment (by tscrim):
Thank you for looking at this.
I made that a lot shorter because (IMO) this class does not deserve any
real documentation because it is hidden from the doc and never exposed to
the user. You are only going to see this if you are looking at the code,
but it is clear from the code what this class does. I feel it is just an
implementation detail because of how we handle posets.
There is only one maximal element because the Möbius algebra is only
defined for lattices.
