Summary
[edit]DescriptionInterlaced-Triangles Brunnian-link alternate.svg |
Three interlaced triangles with curvy sides, forming a quasi-Arabesque pattern which is also a Brunnian link of knot theory. Topologically equivalent to Image:Three-triang-18crossings-Brunnian.png ; is also a revised version of the "star of the muses" symbol... This is an alternative version of File:Interlaced-Triangles quasi-Arabesque Brunnian-link.svg , made from curves based on the quasi-Limaçon/Rose polar coordinates equation r=b+sin(aθ), with parameters b=5/3 and a=3 (see File:Mathematical-polar-equation-flowers.svg ). |
