Abstract

We prove that there exist Salem numbers with trace 3-3 and every even degree 34\geq 34. Our proof combines a theoretical approach, which allows us to treat all sufficiently large degrees, with a numerical search for small degrees. Since it is known that there are no Salem numbers of trace 3-3 and degree 30\leq 30, our result is optimal up to possibly the single value 3232, for which it is expected there are no such numbers.
