I am interested in Number Theory and Algebraic Geometry and I teach Mathematics.

A pandiagonal magic cube of order 7. See
Let m_k be an integer located at position (a, b, c). If for k = 1, ..., 7, the m_k are colinear, then the sum of the m_k is equal to 1204, the sum of the first 7^3 positive integers divided by 7^2. The cube contains 27 distinct magic squares. I found this after reading
A. P. Street, W. Wallis, Combinatorial theory: An introduction, 1977,
and then decided to study mathematics.
