Permutations with repetitions

Question

Is there any inbuilt function in Julia language that permutes a given list with repetitions

There are n^n such permutations for a list of n elements

Agree with Harlan's response. It's a little hard to know what you're looking for since a permutation never includes any repetitions. Permutations are just reorderings of a list. Harlan's suggestion describes Cartesian products, which would have the n^n size you mentioned. — John Myles White, Feb 07 '14 at 14:25

Not entirely sure what you're asking for, but the cartesian product iterator in the Iterators.jl package might be along those lines.

(Not inbuilt, if that matters to you for some reason. Also, Iterators.jl could use better documentation...)
