Try this code:
from sage.graphs.connectivity import vertex_connectivity
G=Graph({1:[2,3,4,5],2:[1,3,4,5],3:[1,2,4,5],4:[1,2,3],5:[1,2,3]})
vertex_connectivity(G,value_only=False)
The result, running in a SageCell Server is
(3, [1, 2, 3])
Which says the vertex connectivity is 3 and the vertices 1,2,3 are such a set.
The documentation for vertex_connectivity() is here.
