> [math]A = B = C[/math] implies that [math]A \Delta B \Delta C = \emptyset[/math]
It doesn't. Consider that [math](A \Delta A)\Delta A = \emptyset \Delta A = A[/math].
Same thing applies for the first condition you gave.
The obvious condition is [math]A \Delta B = C[/math], since [math]D \Delta C = \emptyset[/math] if and only if [math]D = C[/math].

I'm willing to check through it if you do it.
