English: A magic square using unit quaternions. The complex number i cannot be distinguished from the complex number -i. See en:Galois group#Finite Abelian groups: "Gal(C/R) has two elements: the identity automorphism and the complex conjugation automorphism." Originally, I planned to use +1, -i, -j, +k values only for the binary decompositions of the values from the middle of de:Vollkommen perfektes magisches Quadrat#Beispiele 09 → 9-1 = 8 = 1000 would have been +1, etc.
