In geometry, the order-7 truncated triangular tiling, sometimes called the hyperbolic soccerball, is a semiregular tiling of the hyperbolic plane. There are two hexagons and one heptagon on each vertex, forming a pattern similar to a conventional soccer ball (truncated icosahedron) with heptagons in place of pentagons. It has Schläfli symbol of t{3,7}.

  • En geometrio, la ordo-7 senpintigita seplatera kahelaro estas kahelaro de la hiperbola ebeno. Kiel la nomo sugestas, ĝi povas esti farita per senpintigo de la regula ordo-7 triangula kahelaro. En la kahelaro estas unu seslateroj kaj du (seplateroj, seplateras) ĉirkaŭ ĉiu vertico. Ĝia simbolo de Schläfli estas t1,2{7,3}. (eo)

  • 在幾何學中,截角七階三角形鑲嵌(英語:Triheptagonal tiling)是一種僅能被構造在雙曲面上的正多邊形鑲嵌,是半正鑲嵌的一種,由正七邊形與正六邊形拼合,並且將正七邊形與正六邊形重複排列組合,並讓圖形完全拼合,而且沒有空隙或重疊的幾何構造。每個頂點皆由兩個正六邊形與一個正七邊形構成,在施萊夫利符號中用t{3,7}表示;此外由於結構類似於足球(僅差在足球的正五邊形改成正七邊形),因此又被稱為雙曲足球(英語:hyperbolic soccerball)。足球是截角二十面體,可以視為五階三角形鑲嵌經截角變換後的像,與截角七階三角形鑲嵌非常類似,但截角二十面體是球面鑲嵌,截角七階三角形鑲嵌是雙曲面鑲嵌。 (zh)
