Comments

The orphelins are the union of 5 numbers (1 - red, 20 - black, 14 - red, 31 - black, 9 -red) in a first sector and of 3 numbers (17 - black, 34 - red, 6 - black) in another sector. The two disjoint sectors separate the "Voisins du Zéro" (neighbors of zero) sector from the "Tiers du Cyclindre" (one third of the wheel) sector.
