A tactical con guration consists of a nite set V of points, a nite set B of
blocks and an incidence relation between them, so that all blocks are incident
with the same number k points, and all points are incident with ...
Codes, graphs and designs from maximal subgroups of alternating groups
(University of the Western Cape, 2018)
The main theme of this thesis is the construction of linear codes from adjacency matrices or sub-matrices of adjacency matrices of regular graphs. We first examine the binary codes from the row span of biadjacency ...
