I have seen f = sympy.symbols('f', cls=Function) but not any documentation. Python does not like x = sympy.symbols('x', cls=FF(8)), it complains about
raise CoercionFailed("expected an integer, got %s" % a) CoercionFailed: expected an integer, got x
Whan is the purpose of the cls parameters and what must I do so that cls=FF(8) is meaning full?
With x = sympy.symbols('x', cls=FF(8)) I want x to be a symbol in the field FF(8), i.e x^(2^8-1) must give me 1.
