No. The given numbers do not satisfy the Euler characteristic for a simply connected polyhedron.
It must be a very strange shape. The numbers do not satisfy the Euler characteristic for any simply connected polyhedron.
An octahedron (not octohedron) is a polyhedron with 8 faces. There are 257 distinct topological octahedrons and the number of vertices and edges varies.For example, an octahedron in the form of a quadrilateral based bipyramid has only 12 edges whereas a hexagonal prism has 18.
There can be no such polyhedron since the given numbers are not consistent with the Euler characteristic.
An octahedron has8 faces, 12 to 18 edges and 6 to 12 edges.
12 vertices and 18 edges.
An hexagonal cross-section prism has 8 faces, 18 edges and 12 vertices
All convex ten-faced polyhedra meet this criteria, and perhaps other polyhedra as well. There are several solutions, including: the polyhedron the half truncated cube: it has 24 edges.The octahedral prism has 24 edges.The square anti-prism 16 edges.The pentagonal bipyramid has 15 edges.The nonagonal pyramid has 18 edges.
