 It has Coxeter diagram , and symmetry , order 800.The uniform "10-10 duoprism" can be constructed from [10]×[10] or [5]×[5] symmetry, order 400 or 100, with extended symmetry doubling these with a 2-fold rotation that maps the two orientations of prisms together.The regular complex polytope 10{4}2, , in formula_1 has a real representation as a 10-10 duoprism in 4-dimensional space.
