When I consider a cycle graph (directed graph), I think the removal of some desired edges is logical. But, If I refer that graph as a plane graph, that mean as a face
then Do the removal of some edges logical with the term face?
Because, I feel the face is a closed entity, so that the term face can not be used when removing edges, in that sense do you think the term cycle is better than face.
What ever the terms face or cycle, my end results are not changing, what is only changing is the explanation.
Please answer me.
