482:, my intention was not to make a clear drawing of that specific eight-vertex graph (I think the other one is better for that), but rather a drawing that would show the structure of De Bruijn graphs more generally — the same style of drawing generalizes to binary De Bruijn graphs of any dimension. As I wrote
539:
This phrasing is not very clear to me, but I think that the mathematical description of the set of directed edges has the edge pointing the other way? (e.g the edge goes from the vertex where we shift all of the elements one to the left (v1...vn) to the vertex with the additional character at the

How about "If one of the vertices 'v' can be expressed as another vertex 'w' by shifting all 'w's symbols by one place to the left, dropping the leftmost symbol and adding a new symbol to the right, then 'v' has a directed edge to 'w' . ? -- 20 April 2012
505:(later:) I found some published work supporting the dynamical systems analogy and used it as the basis for moving the figure into a new section describing that connection. Feel free to draw something else as the main illustration for the page. —
451:
Agree - there should either be a description of what 'w' means in this context, or let's lose the set-builder notation. I for one didn't find the set of edges helpful, whereas the properties and descriptions were much

states: "In Dutch, all particles like "van", or "de", or "der", or "ter" in a surname are always capitalized unless a given name or initial precedes it." So shouldn't the "d" be capitalized? (A

Didn't I read somewhere that mathematics can't be discovered? I mean graphs aren't exactly like animal species where they're waiting in some ethereal plane to be discovered by mathematicians.

Shouldn't the definition of "E = ..." end with "v_n = w_n", instead of "v_n = w_(n-1)"? With n-1, it doesn't fit the description. -- 27 May 2007

Actually the same goes for the Edges abstract example following. It is not at all clear what this means as the description permits ambiguity.
