Abstract
A handicap distance antimagic labeling of a graph G=(V,E) with n vertices is a bijection f:V→{1,2,…,n} with the property that f(xi)=i and the sequence of the weights w(x1),w(x2),…,w(xn) (where w(xi)=xj∈N(xi)∑f(xj)) forms an increasing arithmetic progression with difference one. A graph G is a {\em handicap distance antimagic graph} if it allows a handicap distance antimagic labeling. We construct (n−7)-regular handicap distance antimagic graphs for every order n≡2(mod4) with a few small exceptions. This result complements results by Kov\'a\v{r}, Kov\'a\v{r}ov\'a, and Krajc~[P. Kov\'a\v{r}, T. Kov\'a\v{r}ov\'a, B. Krajc, On handicap labeling of regular graphs, manuscript, personal communication, 2016] who found such graphs with regularities smaller than n−7.</p
