[split] Verbose cipher?

By "presence of common groups" do you mean the bigrams themselves or that such bigrams are meaningful units?

I mean that these bigrams are well known features with very high instance counts. It's not hard to notice that these groups are rarely found reversed, e.g. if you remove the 5507 instances of ol you're left with 175 lo instances. Similarly, qo = 5186, oq = 2.
