What shape is this?

[Trinity]

It seems like an icosahedron, but it has 6 faces on top

Are you asking about a polyhedron? If the figure is not flat, then the triangles are not equilateral, and it could be anything (but is definitely not a regular polyhedron).

If this is only one view, we need to know a lot more. Please tell us all you can about the question.
