<｜begin▁of▁sentence｜>### Instruction:
As a teacher assistant, let's break this down into a more practical scenario. Imagine you are helping a math teacher with some network analysis for a classroom seating arrangement. The students are represented as vertices, and if they are friends or sit close to each other, there is an edge between them. The problem you are trying to solve is to figure out if removing certain students from the seating arrangement will result in disconnecting the class. In this case, you want to check if removing students 1 and 2 will separate the class into two disconnected groups, making them a minimal separator. To do this, you can use the `is_minimal_separator` function from the igraph library.
### Response:
from igraph import Graph

# Define a graph
edges = [(0, 1), (0, 2), (1, 2), (1, 3), (2, 3), (3, 4), (4, 5), (3, 5)]
g = Graph(edges=edges)

# Define a set of vertices to check if it's a minimal separator
vertices = [1, 2]

# Check if the set of vertices is a minimal separator
is_separator = g.is_minimal_separator(vertices)
print('Is the vertex set a minimal separator:', is_separator)
