How many dominoes? 2002-09-13

Dominoes are split into two halves. If you were allowed up to 6 dots on each half, how many options of dominoes could you get?

Dominos 2001-04-28
Mark pose la question :
A standard dominoe set consists of 28 pieces, from double-zero to double-six

  1. Is it possible to arrange all those pieces in a straight line in such a way that the dots of any pair of adjacent pieces match? Please include picture

  2. Is it possible to arrange them in a circle and still meet the conditions in 1?

Triminoes 1998-09-09
Roxanne Hale pose la question :
I am doing an investigation about a game called triminoes (like dominoes). The game is played using triangular pieces of card. Each card has 3 numbers on it. I have to investigate the relationship between the number of trimino cards in a set and the largest number on the cards. I found;

largest no. used 0 1 2 3 4
no. of trimino cards 1 4 10 20 35

I was ginen the formula for this which is:
UN= UN - 1 + 1/2 (n + 1 ) (n+2)

UN=no. of trimino cards n= largest no.

I don't know how to get to this equation I think it has something to do with triangle numbers!
