Cyclotomic Alexander polynomials for periodic L-space knots

Let $K$ be a periodic or freely periodic L-space knot, and let $\Delta_K(t)$ denote its Alexander polynomial. Cyclotomic Alexander polynomial conjecture. $\Delta_K(t)$ is a product of cyclotomic polynomials. The paper presents this as a conjecture motivated by computational evidence and proves the corresponding assertion for freely periodic L-space knots of genus at most $16$; the general statement remains unresolved in the supplied text.
