It is known that the connectivity of any \$k \$regular \$(k≤4)\$ connected vertex transitive graph attains its regular degree \$k.\$ Here we show that the connectivity of any 5 regular connected vertex transitive graph is 5 unless it is isomorphic to \$C\-nK\-2
\$ the lexicographic product of the cycle \$C\-n(n≥4)\$ of length \$n\$ and the complete graph \$K\-2\$ on two vertices.
