Small orders of Hadamard matrices and base sequences
We update the list of odd integers n<10000 for which an Hadamard matrix of
order 4n is known to exist. We also exhibit the first example of base sequences
BS(40,39). Consequently, there exist T-sequences TS(n) of length n=79. The
first undecided case has the length n=97.Comment: 7 page
