TWO FAMILIES OF STRONGLY WALK REGULAR GRAPHS FROM THREE-WEIGHT CODES OVER Z 4

Résumé

A necessary condition for a Z4-code to be a three-weight code for the Lee weight is given. Two special constructions of three-weight codes over Z4 are derived. The coset graphs of their duals are shown to be strongly 3-walk-regular, a generalization of strongly regular graphs.
