在幾何學中,開羅五邊形鑲嵌是一種平面鑲嵌,其為半正鑲嵌扭稜正方形鑲嵌的對偶鑲嵌[1],密鋪於歐氏平面,其名為「開羅」是因為這種幾何圖形經常在埃及開羅的街道上出現[2][3],是15種已知的等面五邊形鑲嵌之一。
它也被稱為麥克馬洪網格(MacMahon's net)[5],出於珀西亞歷山大麥克馬洪1921年出版的《New Mathematical Pastimes》[6]。
在化學中
五邊石墨烯的化學結構與開羅五邊形鑲嵌接近[7]這種形態建基於分析和模擬,在2014年被提出。[7]進一步的計算顯示純粹以此形態存在的碳是不穩定的,[8]但將其氫化後可變得穩定。[9]由於其結構,它罕見地具有負值蒲松比,強度相信比石墨烯高,且據預測它能在高達1000K時仍為化學穩定。[7]
