d120 and d48
One-hundred-twenty-sided and Forty-eight-sided Dice
The d120 is the ultimate fair die allowed by Mother Nature (i.e., mathematics)! The d120 is based on a polyhedron known as the disdyakis triacontahedron. The d48 is based on a polyhedron known as the disdyakis dodecahedron. For both dice, each face is an elongated triangle. These dice are perfectly numerically balanced, with the same sums for numbers around vertices of the same type. The dice are available in white, black, red, blue, and green. They are available at The Dice Shop at Mathartfun.com. Click here to learn more about the design.
The d120 can be used as a dn, where n is any proper factor of 120, including all of the dice in a standard seven-dice polyset. Click here for more information.
