Figure 10.12: 173 embedded groups involved in incidents with radical groups
The subset of groups associated with violent action contains 1895 members.
Since the relationships of weakly connected nodes tend to occupy the more significant dimensions in the embedding, we select the subset of those connected to at least
20 others, resulting in a subset of 65 nodes. The positive and negative embeddings
are shown in Figures 10.17 and 10.18. Again, constellations of groups in mutual op-
