This die gives all the permutations of 3 three first letters: a, b and c.
Say, in a RPG, you want to choose which event among three will occur first or which character (among three) will enter first in a room or simply which one among three players will play first, just call them a, b and c, and roll the die. The letters of the upper face will determine the chosen order.
A D24 allowing to choose the order of 4 elements (abcd) is on its way...
