Comment (by jmantysalo):
I understand everything until the end. There is an example with `P(2) <
P(3)`. However, this is just the part where difference between facade and
non-facade sets could be shown. For example we define poset where 2<1:
{{{
P=Poset({2:[1]}, facade=False)
Q=Poset({2:[1]}, facade=True)
print 2 < 1
print P(2) < P(1)
print Q(2) < Q(1)
# Maybe also P.unwrap(P(2)) < P.unwrap(P(1)) here?
}}}
It is unnecessary to know that MuPAD was first system with facade sets.
Authors-field should be filled.
