Comments

Apparently this is the main table for odd numbers of the shell model of partitions. It appears that the table shows an overlapping of all the heads of last sections of partitions of all odd numbers. This is the table 2.1 mentioned in A135010, a geometric version of the table A182743. For even numbers see A182982. The largest parts of the rows of the diagram give A182733.
