Rank-four hyperplane intersection

Determine whether two hyperplanes in a rank-four oriented matroid can always be intersected as required by the relevant intersection property.

Background

The ability to intersect two hyperplanes in rank four would imply the equivalence of the intersection properties discussed in the paper and would support the bound of four adjacent mutations for uniform rank-four Euclidean oriented matroids.

References

Can we always intersect two hyperplanes in a rank $4$ oriented matroid?
