As noted above, you can easily use a fallback database/algorithm if it fails. 48 48 49 BTW, fmpz_mat_hadamard succeeds for every multiple of 4 up to92; current code for the Paley construction in Sage doesn't succeed to construct a size 20 Hadamard matrix.49 BTW, fmpz_mat_hadamard succeeds for every multiple of 4 below 92; current code for the Paley construction in Sage doesn't succeed to construct a size 20 Hadamard matrix.
