Heptahedron.
A hexagonal pyramid.
A heptagon.
A polyhedron is a solid figure with many plane faces, usually greater than six. A polyhedron that has 7 faces is called a heptahedron.
The numbers given do not satisfy the Euler characteristic for a polyhedron. There is, therefore, no such polyhedron.

7 faces
A heptagon has seven sides.

There are a number of possible 7-sided polyhedra. Three that come immediately to mind are: a hexagonal pyramid, a pentagonal prism, a "stretched" triangular pyramid (triangular base, rectangular sides, and then triangular faces meeting at an apex).
The numbers given do not satisfy the Euler characteristic for a polyhedron. There is, therefore, no such polyhedron.
It is a heptagon that is a polygon having 7 sides with 7 interior angles.

This polyhedron has 7 vertices and 12 edges.

A "hectagon" is not actually a shape. You probably confused it with a HEXAGON, which has 6 sides, or a HEPTAGON having 7 sides. Hope this helps!
