Meaning and Definition
A solid figure or crystal form with twenty-four identical triangular faces, constituting an isometric solid.
In geometry and crystallography, a polyhedron that can be considered as a cube with each face capped by a low triangular pyramid, or as an octahedron with each face stellated into three faces. It is one of the Catalan solids, specifically the dual of the truncated cube.

Common Mistakes When Using “trisoctahedron”
- Misspelling as 'trisoctohedron' or 'trisoctahedran'.
- Mispronouncing with primary stress on the first syllable (/ˈtrɪs.../). Correct stress is on 'hee' (/'hiːdrən/).
- Confusing it with a triakis octahedron (which has 24 faces but different face shapes).
FAQ
Frequently Asked Questions
It is a convex polyhedron with 24 identical kite-shaped faces, 24 vertices, and 48 edges. It is one of the 13 Catalan solids.
Almost exclusively in advanced geometry, crystallography (the study of crystal forms), mineralogy, and occasionally in fields like architectural design or computer graphics dealing with complex polyhedra.
The most common pronunciation stresses the 'hee' syllable: tris-okt-a-HEE-dron. In British English, the 'o' in 'octa' is like in 'lot' (/ɒ/); in American English, it's like in 'father' (/ɑː/).
Both have 24 faces. A trisoctahedron (deltoidal icositetrahedron) has kite-shaped faces. A triakis octahedron is created by attaching a triangular pyramid to each face of an octahedron, resulting in 24 isosceles triangular faces. They are different Catalan solids.
A solid figure or crystal form with twenty-four identical triangular faces, constituting an isometric solid.
Trisoctahedron is usually technical / scientific in register.
