Covering the
Aztec Diamond with One-sided Tetrasticks - Preprint:
- Placing the 18 one-sided pentominoes in a 9 x 10 rectangle: There are 10,440,433 different possibilities. The most beautiful solutions (i.e. solutions with the highest symmetry) are shown in this preprint (compressed PostScript). Here is a version in black and white.
