                   Soddy4Tuple

4-Tuple (radius, center, deltas, outer) with radius and trilaterated center of the inner Soddy circle and the radius of the outer Soddy circle. The center is unambiguous if deltas is None, otherwise center is the mean and deltas the differences of the pygeodesy.trilaterate3d2 results.


Note: The outer Soddy radius outer may be INF.
