## Problem 154 — rank:154

**Title:** Suppression of within-group conflict

**Added binding assumptions (LaTeX):**

```latex
Replace an unspecified ``stationary distribution conditional on survival'' by a defined quasi-stationary law, its finite-age conditional analogue, or a regenerative law sampled at group-transfer times. Existence and uniqueness must be checked for the selected process. State the heritability and transfer kernel of policing and evasion traits. Low within-group mutant abundance is not equivalent to low transmission into new groups.
