Hmm. It's a bug which apparently was introduced by #9032 in 4.6.2. This patch adds an alias N -> numerical_approx for each and every Sage object: sage: 13.N() 13.0000000000000 sage: x = gap3(13) sage: x.N() 13.0000000000000 In the CoxeterGroup code, N was overriding the field N of the gap3 record representing the Coxeter group. I worked around this by using x.__getattr__("N"). This seems to work. Pushed. Cheers, Nicolas -- Nicolas M.
