{"product_id":"e7-coxeter-projection","title":"E7: Coxeter Projection","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eE7 is the second-largest of the four exceptional root systems, sitting between E8 and E6 in a family of objects with no straightforward lower-dimensional analogue. It has 126 roots in 7-dimensional space, each one connected to 32 others at the nearest-neighbour distance, giving 2,016 edges in total.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Coxeter plane projection collapses all 7 dimensions into a single plane while preserving the system's 18-fold rotational symmetry. The 126 roots arrange themselves into 7 concentric rings of 18 - a structure that is genuinely visible in the print in a way that E8, with its greater density, makes harder to read. If E8 is the overwhelming one, E7 is the one you can actually study.\u003c\/p\u003e","brand":"Axisophy","offers":[{"title":"Large (50 × 70 cm | 20 × 28 in)","offer_id":45891939729569,"sku":"APW-E7C-P-500x700-AM-WHT","price":50.0,"currency_code":"GBP","in_stock":true},{"title":"XLarge (70 × 100 cm | 28 × 40 in)","offer_id":45891939762337,"sku":"APW-E7C-P-700x1000-AM-WHT","price":80.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0483\/1546\/5889\/files\/Axisophy-E7-Coxeter-mockup-1.jpg?v=1775495758","url":"https:\/\/axisophy.com\/products\/e7-coxeter-projection","provider":"Axisophy","version":"1.0","type":"link"}
