“…However, the situation changes in higher dimension. In fact, it is proved in [1] that there exist spectral sets which are not tiles in F 5 p for all odd primes p and in F 4 p for all odd primes p such that p ≡ 3 mod 4, where F p is the prime field with p elements. This implies that there exist compact open spectral sets which are not tiles in Q 5 p for all odd primes p and in Q 4 p for all odd primes p such that p ≡ 3 mod 4.…”
