The pentagonal-cubic duoprism or pecube, also known as a square-pentagonal duoprismatic prism, is a convex uniform duoprism that consists of 5 tesseracts and 6 square-pentagonal duoprisms. Each vertex joins 2 tesseracts and 3 square-pentagonal duoprisms. It is a duoprism based on a square and a pentagonal prism, which makes it a convex segmentoteron.

- x x4o x5o (square-pentagonal duoprismatic prism)
- x x x x5o (pentagonal prismatic prismatic prism)
