Polytope of the Month
This is the octa-augmented runcitruncated 16-cell, a beautiful polytope that sports 24 elongated square bipyramids (J15) as cells, among other shapes. It can also be considered as one of the partial Stott contractions of the runcitruncated 24-cell, or a Stott expansion of the octa-augmented runcinated tesseract.
