Caps Completed Using a Computer Search
Constructions for caps in the projective space PG(u, b) with b > 2 are given in [1], with two extensions in [2]. Most of these caps are constructed by adding points to known caps until a complete cap is reached. Generator matrices for all these caps can be found at Yves Edel’s home page at http://www.mathi.uni-heidelberg.de/~yves/Matritzen/CAPs/CAPMatIndex.html.
The following caps are included:
Over the Field with Size b = 3
Dimension u | Size | Largest affine sub-cap |
7 | 248 | 236 |
8 | 532 | 476 |
9 | 1216 | 1068 |
