Maak met 2x dezelfde of 2 verschillende magische 7x3 (=3x7) rechthoeken een ultramagisch 21x21 vierkant. Het ultramagische 21x21 vierkant is panmagisch, symmetrisch, 3x3 en 7x7 compact.
Gebruik voor het 1e patroon:
1 | 5 | 14 | 20 | 18 | 10 | 9 |
19 | 16 | 15 | 11 | 7 | 6 | 3 |
13 | 12 | 4 | 2 | 8 | 17 | 21 |
Je kunt voor het 2e patroon dezelfde, maar ook een ander magische 7x3 (=3x7) rechthoek gebruiken, bijvoorbeeld:
1 | 20 | 12 |
5 | 19 | 9 |
14 | 15 | 4 |
16 | 11 | 6 |
18 | 7 | 8 |
13 | 3 | 17 |
10 | 2 | 21 |
