Sans relancer de troll sur les compléments graphiques de l'univers LaTeX... :)
voici une solution avec metapost :)
prologues:=2;
mul:=2;
modulo:=60;
rayon=2.5;
path cercle;
cercle=fullcircle scaled (2*rayon*1cm);
pair A[],O;
O=(0,0);
A0-O=(0,rayon*1cm);
for k=1 upto modulo-1:
A[k]=A[k-1] rotatedabout(O,360/modulo);
endfor;
beginfig(1);
draw cercle;
for k=1 upto modulo-1:
draw A[k]--A[k*mul mod modulo];
endfor;
endfig;
endend
ou voici un code à compiler directement sur overleaf
\documentclass{article}
\usepackage[shellescape]{gmp}
\begin{document}
\begin{mpost}
prologues:=2;
mul:=2;
modulo:=60;
rayon=2.5;
path cercle;
cercle=fullcircle scaled (2*rayon*1cm);
pair A[],O;
O=(0,0);
A0-O=(0,rayon*1cm);
for k=1 upto modulo-1:
A[k]=A[k-1] rotatedabout(O,360/modulo);
endfor;
beginfig(1);
draw cercle;
for k=1 upto modulo-1:
draw A[k]--A[k*mul mod modulo];
endfor;
endfig;
end
\end{mpost}
\end{document}
