Short Sequence Transposition

My random cipher generator picked this short text to encipher as a Sequence Tramp. I’ll provide the primer. With the primer, it’s not difficult to get the plaintext but I was unable to identify the 1-word key. I eventually figured out why. Here’s the ciphertext. I’ll provide a Caesar crib.

  1. I thought the ciphertext was too short to try primerless solving so I used the primer to find the solution. Didn’t need the crib though. But one number in the key has no entries in its column, so that number could be placed anywhere in the key. That gives more key word possibilities than I want to try.

    1. Once I realized what the problem was (i.e., the empty 2 digit) I saw there were only 10 possible positions for it. I just ran my hat finder program in each of the ten positions. Only one word came up – the key.
