The cocyclic Hadamard matrices of order less than 40
In this paper all cocyclic Hadamard matrices of order less than 40 are classi´Čüed. That is, all such Hadamard matrices are explicitly constructed, up to Hadamard equivalence. Thi...

Rooted Trees Searching for Cocyclic Hadamard Matrices over D4t
A new reduction on the size of the search space for cocyclic Hadamard matrices over dihedral groups D4t is described, in terms of the so called central distribution. This new searc...
