εijk is the permutation symbol and cyclic permutations, for example 123→231→312, are always even, thus ε123231312=+1, but:
ε132213321=-1
I understand the first 2, but ε321 is even, no? and also all this series is cyclic, it's not all even and....

Why would ##\varepsilon_{321}## be even?

Oh sorry, right, but my original question is why is it written in a text book that every cyclic permutation is even while the cyclic permutations ε132=ε213=ε321 are odd?
