Consider the following equivalence relation on the set of nxn matrices.
X is equivalent to Y if there is an invertible matrix A so that Y=AXA^t, where A^t is the transpose of A. How can I describe the set of equivalence classes? For instance, what can I take as representatives, or what are invariants?

I understand the problem when X is symmetric or antisymmetric, it is the general case that I'm wondering about.

I'd like to know how to solve this word problem and how the answer is reached:
A football team practices running back and forth on the field in a special way. First they run from one end of the 100 yard field to the other. Then they turn around and run half the previous distance. Then they turn around again and run half the previos distance and so on.
A. Suppose the athletes continue the running drill with smaller and smaller distances. What is the coordinate of the point that they approach?
B. What is the total distance that the athletes cover?
Thank you I appreciate your help all you math genuises! =D

n > 6 and an integer

Prove that if n + 1 and n - 1 are both prime, n^2(n^2+16) is divisible by 720.

Is the converse true, i.e. if n^2(n^2+16) is divisible by 720, are both n + 1 and n - 1 prime?
