- Here's another question I've always wondered about: what is Gauss's Erdos
- number?
-
- It certainly makes sense to ask such a question, since coauthorship can
- extend into the past as well as the future. The answer might be trivial,
- because it is my __impression__ that coauthorship was rare until relatively
- recently. Does anyone know offhand whether Gauss ever coauthored a paper?
- (For that matter, where can one find a list of his publications? Relatively
- short, given his motto.)
