.=====================================================#

For _eight_ letters (adding l) I place, in each of the 16 Cells, a
_lattice_, which is a reduced copy of the whole Diagram; and, just as
the 16 large Cells of the whole Diagram are assigned to the 16 Classes
abcd, abcd', &c., so the 16 little Cells of each lattice are assigned to
the 16 Classes ehkl, ehkl', &c. Thus, the lattice in the N.W. corner
serves to accommodate the 16 Classes abc'd'ehkl, abc'd'eh'kl', &c. This
Octoliteral Diagram (see next page) contains 256 Cells.

For _nine_ letters, I place 2 Octoliteral Diagrams side by side,
assigning one of them to m, and the other to m'. We have now got 512
Cells.
