New description:
Obviously, the instructions
{{{
pp = Permutation([3, 1, 2])
pp.hyperoctahedral_double_coset_type()
}}}
lead to an error because the permutation has an odd size. However, there
is an error in the raised error message :
{{{
NameError: global name 'p' is not defined
}}}
The string should be
{{{
ValueError: [3, 1, 2] is a permutation of odd size and has no coset-type
}}}
