Salut Nicolas,
thanks for your detailed answer!
I implemented, as you suggested, a universal cyclotomic field. The
problem is that this causes dependencies between basis elements. These
are as follows:
- if p divides n: [ ( p*n, p*k ) for (n,k) in ZumbroichBasis( n, 1 ) ]
is contained in
Another question I just thought about was: Do we want:
1. every element in the universal cyclotomic field living in exactly
one cyclotomic field QQ( \zeta_n ) generated by ZumbroichBasis(n,1)
for some n, or
2. can an element have several monomials living in different
cyclotomic fields.
In gap,
Hi all,
is it on purpose that the method LazyFamily does not check membership
when calling __getitem__?

sage: a[4]

KeyError: 100
sage: b = Family( range(10), lambda i:i+2, lazy=True)
sage: b[4]

As some additional points of interest/questions for this problem:
1. Version 2.7.2 was the last Sage version which could be installed.
We tried most versions since then (latest 4.4.2), and they all failed

2. It is always the same package which fails. We don't have any
