Jimmy,
Can you give me the link to the topic on the J programming forum where
Arie
Groeneveld and others discuss verbs that perform all permutations of x size
taken from y items.
You stated that Arie came up with this solution:
vari =: 4 :'y,/@:(],"1 0 -."1)^:(x-1) ,.y'
I would like to see others' solutions to that same problem.
