The uchburchak bifrustum ning cheksiz qatorining ikkinchisi bifrustum polyhedra. Unda 6 bor trapezoid va 2 uchburchak yuzlar. Bundan tashqari, kesilgan uchburchak bipiramida; ammo, bu atama noaniqdir, chunki u uchburchak bipiramidaning beshta tepasini qisqartirish natijasida hosil bo'lgan ko'pburchakni ham anglatishi mumkin.^[1]

Ushbu ko'pburchakni olish yo'li bilan qurish mumkin uchburchak bipiramida va qutb o'qi vertikalarini qisqartirish, uni uchidan uchigacha qilish frustums. Bu aniq shakl sifatida paydo bo'ladi nanokristallar.^[2]^[3]

Kesilgan uchburchak bipiramidani ikkita stakalashtirilgan muntazam ravishda ulash orqali qurish mumkin oktaedra bilan 3 juft tetraedra yon tomonlari atrofida. Bu qismning bir qismini anglatadi o'zgaruvchan kubik chuqurchasi.
