Query: Moduli curves of supersingular K3 surfaces in characteristic 2 with
  Artin invariant 2   We construct explicitly moduli curves of polarized supersingular K3 surfaces
in characteristic 2 with Artin invariant 2. As an application, we detect a
"jump" phenomenon in a family of automorphism groups of supersingular K3
surfaces with a constant N\'eron-Severi lattice.
