Jan 19, 2009 · Abstract: A sequence of reversals that takes a signed permutation to the identity is perfect if at no step a common interval is broken.

A sequence of reversals that takes a signed permutation to the identity is perfect if it preserves all common intervals between the permutation and the ...
