[sage-combinat-devel] Re: #8327 Implement the universal cyclotomic field, using Zumbroich basis

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,

[sage-combinat-devel] Lazy Family membership check

Hi all, is it on purpose that the method LazyFamily does not check membership when calling __getitem__? sage: a = Family( range(10), lambda i:i+2) sage: a[4] 6 sage: a[100] KeyError: 100 sage: b = Family( range(10), lambda i:i+2, lazy=True) sage: b[4] 6 sage: b[100] 102 Do you also think that
