									To solve this problem, you need to decide on a
									reasonable interpretation of the phrase &quot;all
									graphs.&quot;

									obtained from other graphs by simply moving
									vertices, or by stretching edges on the figures that
									represent them? What makes one graph truly
									<b>different</b> from another?
