The entries of the matrix are arranged in such a way that the determinant of the matrix is maximized.
The special case of the first matrix with determinant A180128(5) = 5725998504 is excluded, since the prime number 2 prevents the otherwise existing divisibility of the determinant by 16.
EXAMPLE
a(2) = 445934520: determinant(
[73 53 3 79 23]
[37 101 43 5 47]
[19 41 89 71 13]
[11 31 29 61 97]
[83 7 67 17 59]) = 7134952320 = 16*445934520.
