Bold, warm and quietly clever, it suits a study, an office or a maths lover's hallway.\u003c\/p\u003e\n\u003cp\u003ePart of our Knots and Twists set in the Poster Kingz Puzzle \u0026amp; Science range. The fact behind the art: The trefoil is the simplest non-trivial knot, with crossing number 3. Drawn from the curve x = sin t + 2 sin 2t, y = cos t - 2 cos 2t, z = -sin 3t, with true alternating over and under crossings. Every design is drawn in code from the real data, so the details are right, then printed in our modern palette of cream, navy, terracotta, mustard and teal.\u003c\/p\u003e\n\u003ch3\u003eProduct details\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eExclusive Poster Kingz design\u003c\/li\u003e\n  \u003cli\u003eAvailable in A5, A4, A3 and A2 unframed sizes\u003c\/li\u003e\n  \u003cli\u003eAlso available framed in A5, A4 and A3, ready to hang straight out of the box\u003c\/li\u003e\n  \u003cli\u003ePrinted on premium quality paper stock\u003c\/li\u003e\n  \u003cli\u003eDesigned and printed in the UK by Poster Kingz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSee the rest of the set in our \u003ca href=\"\/collections\/maths-posters\"\u003eMaths Posters\u003c\/a\u003e collection, or browse the whole \u003ca href=\"\/collections\/puzzle-science-posters\"\u003ePuzzle \u0026amp; Science Posters\u003c\/a\u003e range.\u003c\/p\u003e","brand":"Poster Kingz","offers":[{"title":"A5 (unframed) 5.8 × 8.3 in","offer_id":58255744074110,"sku":null,"price":7.99,"currency_code":"GBP","in_stock":true},{"title":"A4 (unframed) 8.3 × 11.7 in","offer_id":58255744106878,"sku":null,"price":9.99,"currency_code":"GBP","in_stock":true},{"title":"A3 (unframed) 11.7 × 16.5 in","offer_id":58255744139646,"sku":null,"price":14.99,"currency_code":"GBP","in_stock":true},{"title":"A2 (unframed) 16.5 × 23.4 in","offer_id":58255744172414,"sku":null,"price":22.99,"currency_code":"GBP","in_stock":true},{"title":"A5 Framed","offer_id":58255744205182,"sku":null,"price":19.99,"currency_code":"GBP","in_stock":true},{"title":"A4 Framed","offer_id":58255744237950,"sku":null,"price":24.99,"currency_code":"GBP","in_stock":true},{"title":"A3 Framed","offer_id":58255744270718,"sku":null,"price":29.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0695\/8989\/3410\/files\/trefoil-knot-print-knot-theory-maths-ribbon-art-poster-1.jpg?v=1792269750","url":"https:\/\/posterkingzuk.com\/products\/trefoil-knot-print-knot-theory-maths-ribbon-art-poster","provider":"Poster Kingz","version":"1.0","type":"link"}
