Mi correggo, deve pure valere il contrario, quindi

1g * (a,b) = (a,b)

e quindi l'elemento neutro dovrebbere essere (a,1), solo che dovrebbe valere per ogni elemento uguale, il che nn avviene. Quindi nn esiste elemento neutro.

è associativa, e si fa cosi

((a,b)*(c,d))*(e,f)=(a,b)*((c,d)*(e,f))

(a,bd)*(e,f)=(a,b)*(c,df)

(a,bdf)=(a,bdf)

chiaro?

el. neutro non la so xchè l'ho sbagliata -.-, c'era da fare per el. sx e el. dx a causa della particolare uguaglianza...
