Sep 23 accepted Can linearly independent vectors have linearly dependent images? Sep 23 comment Can linearly independent vectors have linearly dependent images? Good explanation. Am I correct in thinking that your last sentence only holds when ${\bf u}$ and ${\bf v}$ are linearly independent because otherwise, they could both be the zero vector? Sep 23 comment Can linearly independent vectors have linearly dependent images? Good catch. I meant to say "dependent."

Dec 12 awarded Popular Question Dec 8 comment How many nonisomorphic graphs are there with 10 vertices and 43 edges? Is my third attempt sound? Dec 8 revised How many nonisomorphic graphs are there with 10 vertices and 43 edges? added 318 characters in body Dec 8 comment How many nonisomorphic graphs are there with 10 vertices and 43 edges? So, as clarification, the graphs in bullet point one would still count as one non-isomorphic graph, correct? I've made some revisions to my solution. Dec 8 revised How many nonisomorphic graphs are there with 10 vertices and 43 edges? added 318 characters in body Dec 8 comment How many nonisomorphic graphs are there with 10 vertices and 43 edges? One thing that's tripping me up is that I'm not sure what it means for one graph to be isomorphic. It's usually in the context of two graphs. Is it asking for the number of "non-isomorphic classes"? Dec 8 comment How many nonisomorphic graphs are there with 10 vertices and 43 edges? I think I like this framing better. Dec 8 comment How many nonisomorphic graphs are there with 10 vertices and 43 edges? Would you mind explaining why the former are all isomorphic but not all of the latter are? Dec 8 suggested rejected edit on Graph Theory - How can I calculate the number of vertices and edges, if given this example
