Here is another reason why I think it's a bug: The residue of LargeSchroeder at x=0 is supposed to be the coefficient of x^(-1) in its Laurent series expansion. However, sage: LargeSchroeder.residue(x==0) 0 sage: LargeSchroeder.series(x,6).coefficient(x^-1) -1/2 Best regards, Simon -- You received this message because you are subscribed to the Google Groups "sage-support" group.
