In this paper, we shall consider the following problem: up to duality, is a connected matroid reconstructible from its connectivity function? Cunningham conjectured that this question has an affirmative answer, but Seymour gave a counter-example for it. In the same paper, Seymour proved that a conne

Matroidal families were introduced by SimiSes-Ferefra [S]. Altb~ough we know uncountably many matroidai families of simple graphs and infinitely many matroidal families with multigraphs as members, it is an open question how one can find ail matroidal families. In this paper we give a solution of th
