The numbers of lines (points) of the various types are given in the first row (column) of the table following. The notation follows that given for the 3-dimensional geometry.
| No | 1 | 24 | 48 | |
|---|---|---|---|---|
| No | Name | s | t2 | x |
| 3 | C0 | 3,1 | 1,8 | 0,0 |
| 6 | C1 | 6,1 | 0,0 | 1,8 |
| 64 | C2 | 0,0 | 8,3 | 8,6 |
The complete design above is a BIBD with λ=1.
As the symmetry between points and lines is lost in the detailed breakdown, different subdesigns are available according to whether points or lines are taken as treatments.
