FROM LATTICE TO UNIT CELL

S1 lattice

 

If we start with the lattice, we see that there is often more than one reasonable choice of repeat unit (or unit cell).

In lattice S1, we have shown several.  Although there are rules for selecting the "best" unit cell, for our purposes they are unimportant. Note that each unit cell can be stacked without rotation to fill the surface and form the lattice.
