Combination math
I recognise how I was wrong with the ten in the main confluences (3 choose 3), but I'm not convinced that 4 choose 4 is 20 or 5 choose 5 is 35. Using (n-k-1)!/n!(n-k)! 4p4 is 35 and 5p5 is 126 - potentially it's been shifted down 1? Been too long since I've used these formulae. 218.102.134.75 23:37, 21 February 2024 (UTC)
