In this paper, experiments with the same number of treatments, blocks and plots are considered. It is assumed that the response to a treatment is affected by other treatments, and so the model of the experiment is an interference model with neighbor effects. The aim of this paper is to identify the structure of the left-neighbor matrix of E-optimal design and to give the method of construction of such design.
