by the way, we went down a similar path some time ago when someone asked a related question about hero(n)'s formula: is there a reasonable 4-dimensional interpretation for s(s - a)(s - b)(s - c) ? i don't think anyone posted one.
Having failed to come up with a sensible way to make A^2 = s(s-a)(s-b)(s-c), I wonder occasionally: what about Ar = (s-a)(s-b)(s-c)? Three dimensions might be easier than four :-). -- g
