## Abstract In this paper, we study the Mordell‐Weil lattices of the family of elliptic surfaces which is arising from the __E__~8~^4^ singularity, one of the __ADE__ singularities in characteristic 2. And we construct a subfamily of the universal family of supersingular __K__ 3 surfaces in charact
