Problem Description
Generate three integers , , and in with equal probability independently, and use them as the three right-angle side length of a right-angled tetrahedron. Find the expectation of the
reciprocal square
of the distance from the right-angle apex to the slope (Euclidean distance).
For each test case, output a line containing the answer mod .
Input
In the first line, you should read an integer denoting the number of test cases. In every test case, the only line will include an integer . It is guaranteed that is no larger than and is no larger than .
Output
For each test case, output the only line containing just one integer denoting the answer mod .
