Here is a collection of (presumably) all regular octahedron surface tours with at most 200 vertices. Each one is given a label according to the

number of vertices. The label links to a text file containing the tour presented like a Gauss code for knots,
except that we are not specifying

"over" and "under" crossings, and it also contains the feasible values of *a* and *b*. No extra letters means that the particle moves midways between

parallel grid lines.
"s" or "ss" after (*a*, *b*) means it is skewed to one side to some degree: an "s" tour goes through the centre of every other grid

triangle; an "ss" tour passes the centres on the same side.
An "x" in the label indicates that the graph contains at least one vertex of degree 6. Next

to the label, there is one or more illustration(s) (one for each (*a*, *b*) pair, or skewed variant). These
are also clickable for a better view of each one.
