So, do you think a graph is, or can be "algebraic"?

I'll, um, decorate this poll with some more multichoice questions.

1. A graph with vertices and edges is a formal notation: (y/n)

2. A graph with no edges is algebraic: (y/n)

3. If I want to embed a symmetry group in some graph, there is only one choice of graph: (y/n)
3a. Embedding a group in a graph means the graph's vertex set and edge set are both G-sets. (y/n)

4. An algebraic object is an object that can have (or does have) an algebra defined on it: (y/n)

5: Algebras have operations, usually some kind of additive, and some kind of multiplicative function. If both functions can be shown to be isomorphic, the algebra is a group algebra: (y/n)

6: Algebras can be internal, or external (i.e. globally presented). (y/n)
