Hello. We have the shapes of Prism, Prismatoid, Frustum, Scutoid. What would the shape of the bottom be? I made it using the features of the previous shapes, but it doesn't reflect the geography I wanted. Please imagine it to be how I wanted it to, which is even like a shape should be. What is the name of this shape? Is it a new one? It does not match the Scutoid or the Prismatoid, but has the features of both. Also as well as it reflects the aspects of a Antiprism. But the Antiprism was not included on the Wikipedia page, which I used as the source of my image.
