Magische Quadrate aus siebten Potenzen
Sehen sie auch die erste Seite von Magische Quadrate aus Kubikzahlen


Magic squares of 7th powers are known since 2004-2005, using very big 65536 x 65536 heptamagic squares, durch direktes Erheben der Zahlen in die 7. Potenz.

Aber ist es möglich, kleinere Quadrate aus 7. Potenzen zu konstruieren?? Hopefully, yes! In 2012 and 2013, using similar methods than those already used for squares of 6th powers, Jaroslaw Wroblewski und Toshihiro Shirakawa constructed these squares:

The best known = the smallest known magic and semi-magic are these two squares below from Toshihiro Shirakawa.
In his 144x144 magic square, amazing and fun: the 52 digits of S7 are exactly the 52 first digits of the famous number Pi... YES,  !!!!
But not a coincidence... S7 = T1xT2... and in his construction method, he chose T1 and T2 for that.
