From this page, you can get some images of the combinatorial objects we study. They are available in JPEG (for on-line consultation), in postscript (which allow infinite zoom and gives high-quality images), and in gzipped postcript formats (for transfer purpose).

Most of these images have been obtained using software developped by the group and using Graphviz, a graph drawing tool from AT&T.

• The tilings of a decagon with lozenges, together with the flip relation, see [Lat00].

• L_B(15), i.e. the linear partitions of 15 ordered by the dominance ordering, see [LP99].

• The 15 first levels of the infinite tree T_B(infinity) which contains exactly the partitions of n at level n, defined in [LP99]. This tree allows the enumeration of the partitions of a given integer in optimal time with a very simple algorithm.

• R_2(80), i.e. the set of k-uplets (a_i) such that the sum of a_i.2^i is equal to 80. This is a distributive lattice, and it is equivalent to a special Chip Firing Game, see [].

• SPM(15), SPM(20) and SPM(40), i.e. the linear Abelian Sandpile Model started with 15, 20 and 40 grains in the first column, also equivalent to a special Chip Firing Game, see [LP00] and [LMMP99].
