The implicit parameters must be somehow deducible from the explicit ones - that's the case with 'p' which is reconstructed using 'c'. Otherwise there's no way to specify which 'f' you have in mind when you use 'Sum c'.
And if you mean 'any f', then it must be stated as such in the definiens:

func Sum c -> Element of F2 means
for f being enumeration of vertices(p) ...

or as you propose (which is even better to use later)

func Sum c -> Element of F2 means
for f being enumeration of vertices(p) ...


Of course I meant here:

func Sum c -> Element of F2 means
ex f being enumeration of vertices(p) ...

Best,
