We consider the GF(4)-representable matroids with a circuit-hyperplane such that the matroid obtained by relaxing the circuit-hyperplane is also GF(4)-representable. We characterize the structure of these matroids as an application of structure theorems for the classes of U-2,U-4-fragile and {U-2,U-5,U-3,U-5}-fragile matroids. In addition, we characterize the forbidden submatrices in GF(4)-representations of these matroids. |
