  Let $\mathfrak F$ be a saturated formation of soluble Lie algebras over a
field $F$ of characteristic $p > 0$ and let ${\mathbb F}_p$ denote the field of
$p$ elements. Let $(L,[p])$ be a restricted Lie algebra over $F$ with
$z^{$\scriptstyle [p]$}=0$ for all $z$ in the centre of $L$. Let $S \in
\mathfrak F$, $S\ne 0$ be a subnormal subalgebra of $L$. Let $V, W$ be
$L$-modules. Suppose that the character cluster of $W$ is contained in the set
of ${\mathbb F}_p$-linear combinations of the characters in the character
cluster of $V$. Suppose that $V$, regarded as $S$-module, is $\mathfrak
F$-hypercentral. Then $W$, regarded as $S$-module, is also $\mathfrak
F$-hypercentral.
