Ashraf,

I think if you sit down with a piece of graph paper and
these points in front of you, it will not take you two
minutes to realize that you can easily build *at least*
two or three "unique" arrangements of points that form
closed non-intersecting outlines.

No amount of wishing will make this so. :-)

Cheers,

David
