Choose the parameters : n ; d ; Initial(color) ;colors(number of colors) and press the green flag. ************************************ First look at these parameters : n=2 d=29 n=2 d=39 n=3 d=47 n=4 d= 31 n=6 d= 71 n=7 d= 19 *********************************** Please send me, your better parameter ! ********************************** Mathematical notes:A Maurer rose of the rose r = sin(nθ) consists of the 360 lines successively connecting 361 points. Thus a Maurer rose is a polygonal curve with vertices on a rose. For more information look at Wiki (Maurer rose).
