Asymmetric case

[bvssvni]

The following graph is asymmetric:

Graph { nodes: [Node { core: false, uniq: None }, Node { core: false, uniq: None }, Node { core: false, uniq: None }, Node { core: false, uniq: None }, Node { core: false, uniq: None }, Node { core: true, uniq: Some(9) }, Node { core: true, uniq: Some(9) }, Node { core: false, uniq: None }, Node { core: false, uniq: None }, Node { core: false, uniq: None }], edges: [(0, 7), (6, 7), (2, 6), (2, 3), (3, 4), (4, 5), (1, 5), (0, 1), (1, 2), (5, 6), (7, 8), (4, 8), (0, 9), (3, 9)] }
