Hello, I have a few quick questions: I have Mathematica for students and am trying to create graphs. When I input 19 or less edges, Mathematica returns a graph. But when I try to input 20 or more edges, Mathematica gives no interpretation. Does anyone know how to fix this? Also, some functions such as GraphPlot3D that were stated in a tutorial don't seem to work. Can someone please help?
