The base of a regular pyramid ABCS is an equilateral triangle ABC with side length 6. On the lateral edges BS and CS, points D and E are chosen, respectively, such that |BD | = |CE | and |DE | = 4. The plane ADE is perpendicular to the plane of the lateral face BCS of the pyramid. Calculate the volume of this pyramid.
