About: Order-3 apeirogonal tiling

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In geometry, the order-3 apeirogonal tiling is a regular tiling of the hyperbolic plane. It is represented by the Schläfli symbol {∞,3}, having three regular apeirogons around each vertex. Each apeirogon is inscribed in a horocycle. The order-2 apeirogonal tiling represents an infinite dihedron in the Euclidean plane as {∞,2}.

  • 在幾何學中，三階無限邊形鑲嵌是一種雙曲面的正鑲嵌，由無限邊形組成，在施萊夫利符號中用{∞, 3}表示，即每個頂點周為皆有三個無限邊形，頂點圖可計為∞.∞.∞或∞3。每個無限邊形都內接在極限圓上。 三階無限邊形鑲嵌無法在平面上構造，因為二個無限邊形就已經完全密鋪平面了，即所謂的二階無限邊形鑲嵌，另一個原因是正無限邊形的內角為180度，三個正無限邊形內角為540度，因此無法構造於平面上，但可以在一個雙曲拋物面上構造，另外亦有四階無限邊形鑲嵌和五階無限邊形鑲嵌等雙曲面幾何體。 (zh)
