I am not quite clear in my thinking anymore, but there are 2^2n
permutations, of which (2n choose n) happen to yield the same
effect. These cases are "part of life" and should be counted in
the permutation test just as well. You might save a little bit of
computation time by singling these group-preserving permutations
out, but this is not worth the while at all.
