Fractional Factorial Plans

TLDR
Fractional plans and orthogonal arrays have been extensively studied in the literature, see as discussed by the authors for a survey of some of the most relevant works. But nonexistence of fractional plans has been discussed.

The Existence of Mixed Orthogonal Arrays with Four and Five Factors of Strength Two

TL;DR: In this article, the authors investigated the mixed orthogonal arrays with four and five factors of strength two, and proved that the necessary conditions of such mixed OO arrays are also sufficient with several exceptions.

Non-Orthogonal Designs of Even Resolution*

TL;DR: In this paper, it was shown that the smallest resolution 4 designs for n factors at two levels must contain at least 2n runs, and that "foldover" designs are available with 2 n runs.
