%N 8*a(n) is the maximum possible determinant of a 4 X 4 matrix whose entries are 16 consecutive primes starting with prime(n).

%C The entries of the matrix are arranged in such a way that the determinant of the matrix is maximized.

%e a(1) = 608537 = A180128(4)/8 with the corresponding matrix shown in A180128.

%e a(2) = 837080: determinant (

%e [59 19 23 7]

%e [11 53 37 13]

%e [17 5 43 41]

%e [29 31 3 47]) = 6696640 = 8*837080.
