✦ Synopsis

Hadamard matrices of order n with maximum excess o(n) are constructed for n = 40, 44, 48, 52, 80, 84. The results are: o(40)= 244, o(44)= 280, o(48)= 324, o(52)= 364, o(80)= 704, 0(84) = 756. A table is presented listing the known values of o(n) 0< n ~< 100 and the corresponding Hadamard matrices are constructed. For the remaining values of n = 56, 60, 68, 72, 76, 88, 92, 96 the largest values achieved for the excess are also given.

## Abstract Weaving is a matrix construction developed in 1990 for the purpose of obtaining new weighing matrices. Hadamard matrices obtained by weaving have the same orders as those obtained using the Kronecker product, but weaving affords greater control over the internal structure of matrices co

We show that if there is a skew-Hadamard matrix of order m then there is an Hadamard matrix of order 4m2 -4m whose excess attains the maximum possible bound predicted by S. Kounias and N.

## Abstract We investigate signings of symmetric GDD($16 \times 2^i$, 16, $2^{4-i}$)s over $Z\_2$ for $1 \le i \le 3$. Beginning with $i=1$, at each stage of this process a signing of a GDD($16 \times 2^i$, 16, $2^{4-i}$) produces a GDD($16 \times 2^{i+1}$, 16, $2^{4-i-1}$). The initial GDDs ($i=1$
