Craig's interpolation property in pretabular logics

All pretabular extensions of the minimal logic were described and the tabularity problem was solved earlier. As turned out, in total, there are seven pretabular logics over the minimal logic. It was proved that four of them have Craig's interpolation property (CIP) and two do not. In the present article, we solve the problem of CIP in the seventh logic. We prove that it has Craig's interpolation property.
