Enneagonal-decagonal duoprismatic prism

The enneagonal-decagonal duoprismatic prism or eddip, also known as the enneagonal-decagonal prismatic duoprism, is a convex uniform duoprism that consists of 2 enneagonal-decagonal duoprisms, 9 square-decagonal duoprisms, and 10 square-enneagonal duoprisms. Each vertex joins 2 square-enneagonal duoprisms, 2 square-decagonal duoprisms, and 1 enneagonal-decagonal duoprism. Being a prism based on an orbiform polytope, it is also a convex segmentoteron.
