- The definition of Erdos number clearly implies the existence of the Erdos graph,
- in which the number is sinmply distance from Erdos.
-
- 1) observe that this graph is undirected in mathematics, but directed (by the
- order of the author's names on the paper) in most sciences. Does this allow any
- interesting generalisations?
-
- 2) are there (among mathematicians) any connected components of size greater than
- one not connected to Erdos.
