- En geometrio, triangula dutrunko aŭ triangula senpintigita dupiramido estas pluredro, la dua en malfinia serio de dutrunkoj. Ĝi havas 6 trapezajn kaj 2 triangulajn edroj. Ĉi tiu pluredro povas esti konstruita per preno de triangula dupiramido kaj senpintigo de la apeksaj (polusaj aksaj) verticoj, farante el ĝi kunaĵon de du trunkoj bazo al bazo. (eo)
- In geometry, the triangular bifrustum is the second in an infinite series of bifrustum polyhedra. It has 6 trapezoid and 2 triangle faces. It may also be called the truncated triangular bipyramid; however, that term is ambiguous, as it may also refer to polyhedra formed by truncating all five vertices of a triangular bipyramid. This polyhedron can be constructed by taking a triangular bipyramid and truncating the polar axis vertices, making it into two end-to-end frustums. It appears as the form of certain nanocrystals. A truncated triangular bipyramid can be constructed by connecting two stacked regular octahedra with 3 pairs of tetrahedra around the sides. This represents a portion of the gyrated alternated cubic honeycomb. (en)
- 在幾何學中，雙三角錐台是雙錐台的一種，指二個三角錐台底面語底面相皆所組成的立體，或是雙三角錐被二個平行平面所截位於二個平面中間的立體圖形。每個雙三角錐台皆有6個梯形和2個三角形。 雙三角錐台可以是一種分子構形，如金-銀奈米粒子構形。 雙三角錐台可以透過用三對雙三角錐（二個正四面體）包住二個迪在一起的正八面體來構造。這代表了扭動交替立方體鑲嵌的一部分。此外該種形狀的面皆為正多邊形，但有共面因此也是擬詹森多面體的一種。 雙三角錐台是詹森多面體雙三角錐柱的對偶多面體。 (zh)
