Re: Distinct subsets question
This is just n choose x, which is n!/(x!(n - x)!)
Blood-red were his spurs i' the golden noon; wine-red was his velvet coat,
When they shot him down on the highway,
Down like a dog on the highway,And he lay in his blood on the highway, with the bunch of lace at his throat.
Alfred Noyes, The Highwayman, 1906.
