A surprising and little-recognized property of rhyming, end-to-end palindromic verse is that, contrary to intuition, the order of the lines in such verse may often be transposed in a number of ways without loss of either rhyme or palindromicity. Such line-order permutations can (a) preserve both the verse's original rhyme and palindromicity schemes, (b) change its rhyme scheme, (c) change its palindromicity scheme or (d) change both its rhyme and palindromicity schemes.
