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.
