幾何學中,擬詹森多面體嚴格凸多面體,其幾乎都是正多邊形,但其中有部分或全部的不是正多邊形但很接近正多邊形。 而擬詹森多面體經常會在正多邊形與非正多邊形之間有物理構造上可以忽略的微小差異[1]。近似的精確值取決於這樣一個多面體的面逼近正多邊形的程度。

共面擬詹森多面體

[编辑]

有些未能成為詹森多面體的候選多面體是因為其存在有兩個以上共面的面,其也可以算是全部由正多邊形組成的凸多面體,只是其凸為非嚴格凸。[2]這些多面體可被看做是凸的面且非常接近正多邊形。這些立體通常有無限多種,但若約定所有頂點要位於頂角處,不能位於面(共面的一組面視為同一個面)的內部,則滿足條件的立體只有78個,可以視為詹森多面體的自然推廣[2](參見條件邊正多邊形凸多面體)。

例如: 3.3...:

4.4.4.4:

3.4.6.4:

條件邊正多邊形凸多面體
部分的條件邊正多邊形凸多面體
側錐雙新月雙罩帳

二側錐八面體

正三角錐反角柱

柱化異相雙三角柱

若將詹森多面體的條件放寬成允許面兩兩共面,且所有頂點都要嚴格位於頂角上,不能有邊兩兩共線的情況(若允許邊兩兩共線,則結果會有無窮多種情況),也不能夠有頂點位於共面區域內部的情況,則能夠再列出有限個有此特性的立體。條件邊(conditional edges)指的是對應棱的二面角為平角的邊。[2]在這條件下,能允許互相共面的面有正三角形與正三角形(3+3)、正三角形與正方形(3+4)、正三角形與正五邊形(3+5)、正方形和兩個位於對側的正三角形(3+4+3)、正五邊形和兩個不相鄰的正三角形(3+5+3),也就是說,這些立體除了有正多邊形面外,也會存在上述組合之形狀的面。[3]這類立體一共有78個。[2]和詹森多面體一樣,這些立體除了一些基本立體外,都能夠用柱體、錐體和28種立體互相組合而成。[3]
