Article : Dominos sur grilles trouées - Colegiul National B.P. Hasdeu (Buzau, Roumanie)

Résumé de la production
In this paper we will study the possibilities of covering a square grid with 2x1-sized dominos. The grid may contain zero or an arbitrary number of missing cells. We want to cover this grid with dominos, without skipping, leaving blank spaces and without covering the supposed holes of the grid. Of course, two dominos cannot overlap.
