<｜begin▁of▁sentence｜>### Instruction:
As a smart home designer, you may want to know if a particular grouping of devices in a smart home forms a minimal separator in the network. This could help in identifying key devices that, when compromised, might disrupt the functioning of the entire system. For instance, in a smart home comprising various interconnected devices such as security cameras, thermostats, and lighting systems, it is crucial to identify if a specific combination of devices forms a minimal separator, potentially leaving the rest of the system vulnerable to disruption.
### Response:
import igraph as ig

# Create an example graph
g = ig.Graph.Famous('Zachary')

# Define a set of vertices, for example by index
separator = [1, 2, 3]

# Verify if the given set is a minimal separator
is_separator = g.is_minimal_separator(separator)
print(f'The set {separator} is a minimal separator: {is_separator}')
