Webthe matroid. Uniform matroids are precisely those having only one clonal class. A matroid is said to be bi-uniform if it has at most two clonal classes. Of course, this deﬁnition can be generalized to m-uniform matroids for every positive integer m. A bi-uniform matroid is determined by its rank, the number of elements in each clonal Web24 mrt. 2024 · Roughly speaking, a matroid is a finite set together with a generalization of a concept from linear algebra that satisfies a natural set of properties for that concept.
