Call a $p$-group $G$ *good* if for each subgroups $H, H_1, H_2\subseteq G$ for which $H_1\cup\ H_2\subseteq H$, $|H_1| = |H_2| = |H|/p$, $H'\not=\{e\}$ holds we have that there exists a subgroup $H_3\subset H$ such that 1, 2, 3 holds 1. $|H_3| = |H|/p$ 2. $H_3\cap H_1 = H_3\cap H_2 = H_1\cap H_2$ 3. $c(H_3)\geq c(H) - 1$, where $c(\cdot)$ denotes the nilpotency class of a group. Is it true that for each $p\not= 2$, $N\in\mathbb{N}$ there exists a good $p$-group $G$ with $c(G) \geq N$?
