Query: On hyperbolic cobweb manifolds   A compact hyperbolic "cobweb" manifold (hyperbolic space form) of symbol
$Cw(6,6,6)$ will be constructed in Fig.1,4,5 as a representant of a presumably
infinite series $Cw(2p,2p,2p)$ $(3 \le p \in \bN$ natural numbers). This is a
by-product of our investigations \cite{MSz16}. In that work dense ball packings
and coverings of hyperbolic space $\HYP$ have been constructed on the base of
complete hyperbolic Coxeter orthoschemes $\mathcal{O}=W_{uvw}$ and its extended
reflection groups $\bG$ (see diagram in Fig.~3. and picture of fundamental
domain in Fig.~2). Now $u=v=w=6 (=2p)$. Thus the maximal ball contained in
$Cw(6,6,6)$, moreover its minimal covering bal l (so diameter) can also be
determined. The algorithmic procedure provides us with the proof of our
statements.
