I don't understand this. Don't you get 36 results out of d6xd6? How did you get to 20 results?
since a 4x2 = 2x4, the order of the dice don’t matter, so if a red die rolls 4 and a blue die rolls 2, the result is not distinct from red 2 blue 4!
Oh, I'm looking at dice combination, kinda! I see. Good for a game to practice math too! Haha
