It could be an octagonal based pyramid
An octagonal based pyramid has 16 edges and 9 vertices.
A triangular based pyramid has 4 facxes, 4 vertices and 6 edges
A quadrilateral-based pyramid has 5 vertices, 8 edges and 5 faces
A triangular based pyramid has 6 edges, 4 faces and 4 vertices
It depends on the configuration. Here are some: A nonagon-based pyramid will have 18 edges and 10 vertices; An octagon based prism will have 24 edges and 16 vertices; A pentagon-based dipyramid will have 15 edges and 7 vertices. There are others.
