Bo Die

Recently an ancient 14 sided die was discovered that is used in the Chinese game of Bo. (https://www.scientificamerican.com/article/ancient-board-game-found-in-looted-china-tomb1/) I had to make a net, just because. As I was making it, I had so many questions. What type of polyedron is this, what happens when all the lengths are the same, what's the difference in probability between the hexagon and the square, etc. Then I noticed that the hexagon can have smaller or larger area than the square - which means there's a point where the areas are equal! Did the ancient Chinese dice makers find this balance? How would you check? They numbered like so: "Twelve faces of the die are numbered 1 through 6 in a form of ancient Chinese writing known as "seal script." Each number appears twice on the die while two faces were left blank, the researchers noted." So you wouldn't need equal area faces! How would you number the faces for Bo? How would you number them for 1 to 14?
