Minimum Count in Group
At least N cells in the named group are Suspects (or Innocents). This is a lower-bound constraint (≥ N), so it can never be violated by having more than N. It rules out the possibility that the group contains fewer than N. By itself it cannot force an exact count, so pair it with an upper-bound source such as a total-grid count or an exact count in a complementary group. A frequent error is failing to act on this clue when it directly conflicts with an already-deduced set of Innocents in the same group.
