Cool post btw. for the problem of the week. do you mean visiting the marked points ONCE? or just visiting all marked points without thinking if we crossed them twice or more?
Seconding this, clarification on the constraints of the PotW requested. In addition to once or more visited, to confirm, we can _only_ walk the face diagonals, and not the edges of the cube? And, can we "zig-zag" while walking the face diagonals, moving from a vertex, to the center point, making a 90 degree turn, and moving to a new vertex? Or, can we only travel from one corner to the diagonal opposite with each move?

Same question. Because if it isn't once the answer is obviously yes
