M Theory Lesson 261

In general, the Fourier transform of a magic circulant sum takes the form The condition that it be in $U(1) \times SU(2)$ reduces the number of parameters to four, as in where it is assumed that $B^2 + C^2 = 726$. For the CKM matrix $V$, we have seen that the parameters $A$, $B$ and $C$ are very simple numbers satisfying such rules. $X$ is a small parameter ($X < \sqrt{3}$) that we might adjust to fit the experimental values.
