I would be fairly astonished if allowing singles helped with this problem
(# of extents for the 41). But I too would be very interested to see what
else comes up if they are allowed. I have already mentioned to Richard an
algorithm which ought to allow a search with singles. I would guess it
will be a feasible search for the 41 - I don't know about the 147.
