Mathematics is full of conjectures and theorems, but some of them have been disproved.
Mathematics is full of conjectures and theorems, but some of them have been disproved. F15PE, identify the following failed conjectures related to number theory.  A. It states that every polyhedron has a Hamiltonian cycle through all of its vertices and would have been significant because it would have implied the four color theorem, if it had been true. It was disproved by W.T. Tutte using a polyhedron with 25 faces, 69 edges, and 46 vertices.
