  The dodeca symmetry is designed to obtain the Cabibbo angle $\theta_C^{\rm
CKM}$ approximately $15^{\rm o}$ and the (11) element of $\Vp$ as $\cos 30^{\rm
o}$, leading to $\theta_1^{\rm PMNS}+\theta_C^{\rm CKM}\simeq 45^{\rm o}$. This
leading order dodeca symmetric $\Vp$ is corrected by small parameters,
especially as an expansion in terms of a small parameter $\beta$. Neglecting
two Majorana phases, the expression of $\Vp$ contains four parameters: a small
$\beta$, and three $\Od(1)$ parameters $A,B,$ and $\delta$. From the neutrino
oscillation data, we present two parametrizations and estimate their $\beta$'s.
