Such a shape cannot exist in ordinary 3 dimensional space.

Congruent shapes.
A cube and a regular octahedron have the same number of edges, vertices, and faces. Both have 12 edges, 8 vertices, and 6 faces.

According to Euler none; for all 3d shapes: Vertices + Faces = Edges + 2 ⇒ 12 + 8 = 19 + 2 ⇒ 20 = 21 So unless 20 does equal 21, no 3d shape has 8 faces, 19 edges and 12 vertices. Any 3d shape with 8 faces would be an octahedron.
Each cube has 6 faces, 12 edges and 8 vertices, so two [unconnected] cubes have 12 faces, 24 edges and 16 vertices (between them).
