One of the mainly interesting things of matroid theory is the representability of a matroid. Finding the set of all excluded minors for the representability is the solution of the representability. In 2000, Geelen, Gerards and Kapoor proved that is the complete set of GF(4)-representability. In this paper, we show that is an excluded minor for GF(4)-representability.
