Three hexagons and the twenty-eight first strictly positive integer numbers -nine of them being prime numbers- [Trois hexagones et les vingt-huit premiers nombres entiers strictement positifs -neuf d'entre-eux étant des nombres premiers-].




A structure (white dotted lines) is built using three contiguous hexagons. This structure has V=3*6-((3*1)+(1*2))=13 different vertices and S=(3*6)-(3*1)=15 different sides. The N=V+S=13+15=28 first strictly positive integer numbers {1,2,3,...,28} are located on this structure with the following constraints: The colored lines (starting with 1 -red, at the center of the structure- and ending with 28 -yellow, in the middle right-) display the natural order of the integer numbers.
