Associates in Groups:

All the instances of a particular possible in a Row, Column or Box are confined to one Group forcing some other Possibles in the Group to be impossible solutions.

In this example, all the 4's in the bottom Row are confined to one Group (the Group totalling 20). This means there must be a 4 somewhere in this Group, causing some some impossible solutions (outlined in orange).
