If $(\mathrm{a}\times \mathrm{b})\times \overline{\mathrm{c}}=\overline{\mathrm{a}}\times (\overline{\mathrm{b}}\times \overline{\mathrm{c}})$, where $\overline{\mathrm{a}},\overline{\mathrm{b}}$ and $\overline{\mathrm{c}}$ are any three vectors such that $\overline{\mathrm{a}}\cdot \overline{\mathrm{b}}\ne 0$, $\overline{\mathrm{b}}\cdot \overline{\mathrm{c}}\ne 0$, then $\mathrm{a}$ and $\mathrm{c}$ are
