I would have thought that A.monomial(L) where L is either a listor
tuple of the right length would be a very natural thing to add for
multivariate polynomial rings. You could define your own as a
work-around:
sage: def monomial(A,L):
return A({tuple(L): A.base_ring().one_element()})
sage: mo

The argument is a python dict, which you should read up about for more
details.
Thanks, that's exactly what I needed to know!

Thanks for very fast answer! This works, but import_statements(Posets)

I recently learned that if A is a polynomial ring in Sage in variables x,
y, and z, the command
A({tuple([1,1,1]):1})
returns x*y*z.
Can somebody explain this syntax to me? I understand tuple([1,1,1]), but
what are the curly brackets and the colon doing?
Also, is there a reason that A.monomi

I would like to precalculate something and use cython for that. For
example:
N=7
L = [ P for P in Posets(N) if min([len(P.lower_covers(a)) for a in
P.maximal_elements()]) >= 4 ]

(Then later I can load 'L' and do some calculations with those posets
