Abstract
We show, in this third part, that the maximal number of singular points of a normal quartic surface X ⊂ P3K defined over an algebraically closed field K of characteristic 2 is at most 12, if the minimal resolution of X is not a supersingular K3 surface. We also provide a family of explicit examples, valid in any characteristic.
