{"version":"1.0","type":"rich","title":"Schl\u00e4fli symbol \u2721\ufe0f","description":"Generating polygons with Schl\u00e4fli symbol {p\/q}.\r\n\r\nThe Schl\u00e4fli symbol is a recursive description, starting with {p} for a p-sided regular polygon that is convex. For example, {3} is an equilateral triangle, {4} is a square, {5} a convex regular pentagon, etc.\r\n\r\nRegular star polygons are not convex, and their Schl\u00e4fli symbols {p\/q} contain irreducible fractions p\/q, where p is the number of vertices, and q is their turning number. Equivalently, {p\/q} is created from the vertices of {p}, connected every q. For example, {5\u20442} is a pentagram; {5\u20441} is a pentagon.\r\n\r\nhttps:\/\/en.wikipedia.org\/wiki\/Schl%C3%A4fli_symbol","author_name":"Jurgen","author_url":"https:\/\/turtletoy.net\/user\/Jurgen","provider_name":"Turtletoy","provider_url":"https:\/\/turtletoy.net\/","license":{"fullName":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International","shortName":"CC BY-NC-SA 4.0","url":"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/4.0\/"},"thumbnail_url":"https:\/\/turtletoy.net\/thumbnail\/109a28cd7c.jpg","thumbnail_width":512,"thumbnail_height":512,"html":"<iframe src=\"https:\/\/turtletoy.net\/embed\/109a28cd7c\" width=\"1025px\" height=\"554px\" style=\"max-width: 100%; border: 0\" sandbox=\"allow-scripts allow-top-navigation allow-top-navigation-by-user-activation allow-forms allow-popups allow-same-origin\"><\/iframe>","width":1025,"height":554}
