Permutations for Six Nations final round

THREE POSSIBLE SIX NATIONS WINNERS FROM FINAL ROUND:

* Wales (16 points) will win the title and clinch a first grand slam in seven years if they beat Ireland (14 points) in Cardiff

* If Wales and England (15 points) finish tied on 20 points, which is quite possible, Wales will still be crowned champions, as grand slam winners are automatically awarded three bonus points under Six Nations rules

* A draw between Wales and Ireland - and England losing to Scotland at Twickenham - would give Wales the title without a grand slam

* A draw between Wales and Ireland - and England beating Scotland - would result in England being crowned champions

* If Ireland beat Wales and England defeat Scotland, England will be champions

* If Ireland beat Wales and England lose to Scotland, Ireland will be champions

*** Scotland, France and Italy are consigned to filling the bottom three places.
