Abstract
We construct strongly walk-regular graphs as coset graphs of the duals of codes with three non-zero homogeneous weights over Z<sub>p<sup>m<sup></sub>, for p a prime, and more generally over chain rings of depth m, and with a residue field of size q, a prime power. Infinite families of examples are built from Kerdock and generalized Teichmüller codes. As a byproduct, we give an alternative proof that the Kerdock code is nonlinear.
