Contribution
It introduces a new class of divisible designs from twisted dual numbers and analyzes their combinatorial and geometric properties.

The paper provides a geometric model of these designs in 4-space.
Key combinatorial properties of the designs are characterized.
Abstract
The generalized chain geometry over the local ring of twisted dual numbers, where is a finite field, is interpreted as a divisible design obtained from an imprimitive group action. Its combinatorial properties as well as a geometric model in 4-space are investigated.
