The finished project! Most of half of a complete graph on 36 vertices (even spans only—two disconnected complete graphs on 18 vertices, minus the diameters).
If I can find another bike wheel, maybe next time I’ll try two colors to show the two disjoint graphs.
Work in progress. There’s nothing like actually tying strings to bring greatest common factors into clear focus. Why yes, 12 and 36 do have a common factor! So many triangles. #mathart
A magic tower is a magic square where each cell is represented by a stacked cube of the same length as the cell's number. Here, I have the 3x3 magic square tower added to its mirror image, so that a 3x3x10 box is formed. This is not possible for all magic square configurations, I wonder if there is some kind of formal term for this sort of constraint...
It's #TilingTuesday - Dragon rosette. Consists of 253 equilateral shapes tiled edge to edge without any gaps. It has 12 pentagons and a needle thin hexa star.
Still on the 'draw a fractal inside another fractal' thing. This is a julia set drawn inside something not entirely unlike a multibrot. Looking spookily organic.
