A subset \(S\) of a group \(G\) is called thick if, for any finite subset \(F\) of \(G\), there exists \(g\in G\) such that \(Fg\subseteq S\), and \(k\)-prethick, \(k\in \mathbb{N}\) if there exists a subset \(K\) of \(G\) such that \(|K|=k\) and \(KS\) is thick. For every finite partition \(\mathca...
