Double value X-Wing

Postby RobReeve » Mon Feb 16, 2009 3:20 am

I think this will work. I see an XWing with the corners defined by a XY Pair. I am however a newbie, padiwan learner, and am unsure of the logic other than on a gut level. I would like comments from some of you jedi solvers.

Also if someone could point me at how to use HTML vice BBCode, it would be appreciated.

Thanks!

I can now see why mhy my example didn't apply (rectangle inside only two blocks).

But now I have niftyanother tool to try and learn - leveraging the type I unique rectangle.
