 All You Ever Wanted to Know About Pascal's Triangle and more 
  For example, in row 3, 1 is the zeroth element, 3 is element number 1, the next three is the 2nd element, and the last 1 is the 3rd element. 
  When all the odd numbers (numbers not divisible by 2) in Pascal's Triangle are filled in (fl) and the rest (the evens) are left blank (white), the recursive Sierpinski Triangle fractal is revealed (see figure at near right), showing yet another pattern in Pascal's Triangle. 
  Go here to download programs that calculate Pascal's Triangle and then use it to create patterns, such as the detailed, rightangle Sierpinski Triangle at the far right.
