Abstract: We produce a family of numerical Campedelli surfaces with $ \mathbb{Z}/6$ torsion by constructing the canonical ring of the étale 6 to 1 cover using serial unprojection. In Section 2 we develop the necessary algebraic machinery. Section 3 contains the numerical Campedelli surface construction, while Section 4 contains remarks and open questions.
