Solution:
The crystal system having the highest and the lowest symmetrises respectively, are cubic and triclinic.
Cubic $ \rightarrow $ Most symmetrical (a = b = c, $\alpha =\beta =\gamma =90^\circ $ )
Triclinic $ \rightarrow $ Least symmetrical ( $a\neq b\neq c,\alpha \neq \beta \neq \gamma \neq 90^\circ $ )
