{{{
sage: complete =
NonCommutativeSymmetricFunctions(ZZ).complete()
sage: I = Composition([1,1])
sage: x =
complete.alternating_sum_of_fatter_compositions(I)
sage: [c.parent() for c in x.coefficients()]
[Integer Ring, Rational Field]
}}}
Of course, all the coefficients should be in the Integer Ring.
