There is no such shape.
A pentagon has five sides and five vertices

A common polygon with five vertices is the pentagon. A common three dimensional shape with five vertices is the square pyramid.
The question is rather confused since a tetracontakaioctagon is a 2-dimensional shape whereas a prism is 3-dimensional. Moreover, [3-dimensional] polyhedra are generally named according to the number of faces that they have and, apart from the tetrahedron, the number of vertices is indeterminate. A pentahedron (5- faces) can have 4 or 5 vertices.

4 vertices in 2 dimensional space has only one face with 4 edges. 4 vertices in 3 dimensional space has four faces with 4 edges. I don't know how to imagine dimensional spaces greater than 3, except with time as the 4th dimension. But even with that I cannot imagine a time vertex.
A pentahedron is a closed 3-dimensional shape with five faces, each of which is a polygon.It can have 5 vertices and 8 edges (quadrilateral based pyramid) or 6 vertices and 9 edges (triangular prismoid).
A 3-dimensional shape. 5 plane faces: 3 rectangular, 2 triangular. Triangular faces parallel to one another. 6 vertices 9 edges
A 5-sided 2-dimensional figure is a pentagon and a 5-sided 3-dimensional shape is a pentahedron.
