The questions are stated too ambiguously.
Question 1: What is meant by positioning of rotors. The position in slots, starting position and rings setting or without ring settings?
Question 2: Same as question 1.
Question 3: This one looks unambiguously.
Question 4: quote: "How many possible start positions exist for the chosen
The question ask for start positions of already chosen reflector itself, not for starting positions of the rest of rotors as is written in the last fretty's post. So the correct answer to this question would be 26 (which, I guess, will not be the same as the required answer as it would be too easy)
Question 5: Again similar ambiguity as in question 4.
quote: "…how many possibilities are there for the start
position of the third rotor"
there are always 26 starting position for any rotor (if we do not count ring settings)
So the answer should be again 26.
Question 6: This one looks unambiguously.
Question 7: quote: "…Enigma machine has four normal rotor slots
and you already chose the order…"
You can not choose the order without firstly choosing 4 rotors. (it is like I said you: You have four unknown numbers, choose their order! …you can not, because it has no sense until you know what the values of these four numbers are. So if I said you: You have four numbers 2,3,5,7 choose their order! Then you can choose for example 3,5,2,7)
So I understand the question as I already chose 4 rotors out of 5 and chose their order in the slots. Then the question is too easy, so I think it was again meant differently than it is stated in the question.
Question 8: This one looks unambiguously.
I hope I was not ambiguous too and would like someone (who perhaps have already solved it) to paraphrase these 8 question (maybe only 5, 3 were fine to me) in an unambiguous way and explicitly stating where rings settings are considered and where are not.
