Hi,

I have the following relation (click on link to view):

http://e.imagehost.org/0187/relation.jpg

And I need help giving a mathmatical definition of this relation. I am also having problems stating if the relation is reflexive, symmetric, transitive or antisymmetric. I also need to state my reasons for this. Another problem I am having is stating whether this is a partial order or an equivalence relation.

Any help would be good.

Thanks in advance if you can help me. (That is of course if anyone actually knows anything about discrete maths.)
