A generalized version of the Hilbert 5th problem, called the
Hilbert-Smith conjecture, asserts that among all locally compact
groups only Lie group can act effectively on manifolds. It follows
from the work of Newman and Smith that it is equivalent to the
special case when the topological group is the $p$-adic integers
group $\widehat{Z}_p= \buildrel{\leftarrow}\over{\lim} \{Z/p^nZ,
\phi_n\}$. Although no effective actions of $p$-adic group on
manifolds has yet been constructed, there do exist $p$-adic group
actions on Menger manifolds. We give a new construction of p-adic
group action on Menger compacta.
