TY - JOUR T1 - Prvočíselné magické čtverce A1 - Křížek, Michal JA - Obzory matematiky, fyziky a informatiky Y1 - 2020 VL - 49 IS - 3 SP - 10 EP - 17 SN - 1335-4981 N2 - According to the GreenTao theorem there exist arbitrarily long arithmetical progressions of a finite length containing only prime numbers. We use this deep mathematical statement to prove the existence of prime number magic squares of an arbitrary order n ≥ 3. Finally, we construct a prime number magic cube 3 × 3 × 3 ER - |
