Sesquitruncated square pyramid

The sesquitruncated square pyramid is a near-miss Johnson solid. Its faces are 4+4 isosceles triangles, 1 square, 4 mirror-symmetric heptagons and 1 quad-symmetric octagon

To construct it, one needs to inscribe a heptagon in every triangle and an octagon in a square of a square pyramid, than fill all the remaining gaps with isosceles triangles, and a square.

Although its edge ratio is higher than 1.1, it is still notable for being the simplest non-degenerate sesquitruncated polyhedron possible.
