Given four non-coplanar points, how many different planes exist that are equidistant from all four points?

(In reply to solution by McWorter)

I'm and idiot!  There are FOUR planes like the Q I constructed, one for each group of three of the four given points.  So the answer is FOUR planes.  I spoke too soon.
