These fractions are exact, not truncations or rounded off approximations. There are 4 variations of runcinations of the tesseract including with permutations truncations and cantellations. There are four degrees of cantellations of the tesseract including with permutations truncations. The road has undergone numerous realignments, extensions, upgrades, truncations, and renamings since the mid-20th century. In addition combinations of truncations can be performed which also generate new uniform polytopes. There are 4 unique runcinations of the 5-simplex with permutations of truncations, and cantellations. There are 8 unique sterications for the 6-cube with permutations of truncations, cantellations, and runcinations. Various truncations and misspellings of her name appeared from time to time. There are three truncations, including a bitruncation, and a tritruncation, which creates the "truncated 16-cell". Polynomial truncations arise in the study of Taylor polynomials, for example. Other partial truncations are symmetry-based; for example, the tetrahedrally diminished dodecahedron. There are four unique truncations of the 5-cube. Both areas were protected by deep truncations into the Wadi el-'Arab. Other service truncations also occur in the system during rush hour service only. Its construction, based on truncations on a blade, has a nearly trapezoidal form.
