Je kunt het 21x21 magisch vierkant opbouwen uit 49 evenredige (semi)magische 3x3 vierkanten. Evenredig betekent dat alle 49 (semi)magisch 3x3 vierkanten dezelfde magische som van (1/7 x 4641 = ) 663 hebben. We gebruiken de rij- en kolomcoördinaten van het 3x3 magische vierkant. Alleen gebruiken we nu als rijcoördinaten niet de getallen 0 t/m 2 maar 1 t/m (49x3 = ) 147 en we verdelen de rijcoördinaten evenredig over de 49 magische 3x3 vierkanten. We gebruiken onderstaande tabel, waarbij we de 7 regels aan de andere 7 regels koppelen om de (7x7x3 =) 147 rijcoördinaten te krijgen:
1 | 4 | 7 | 12 | |
2 | 7 | 3 | 12 | |
3 | 5 | 4 | 12 | |
4 | 2 | 6 | 12 | |
5 | 6 | 1 | 12 | |
6 | 1 | 5 | 12 | |
7 | 3 | 2 | 12 |
Maak nu de 49 (semi)magische 3x3 vierkanten.
