I would expect the function levicivita to take the permutations iterator as an input, so that something like this
Using Combinatorics
vectors = [[1],[2],[2]]
perms = permutations(vectors)
lvtensor = levicivita(perms)
parr = collect(perms)
for i in 1:size(parr)
result += lvtensor[i]*prod(parr[i])
does the Einstein summation that the tensor is used for. What is the actual syntax for this and is it possible to change it to the more proper / intuitive syntax?
