Finally managed to solve this one…
I solved part 2 first which lead automatically to solving part 1.

But I still have no clue whatsoever how the title gives the order for the transposition.
Can anyone who does know send me a pm to enlighten me ?

EDIT: thanks for the pm. Now I understand how it's done.

Dear MTC3 Team,

currently the script for checking the solutions seems to be broken as it accepts no answer. Instead one gets a message

"An error occured while checking your solution. Please try again later, and contact us if this issue persists."

and in German: "Es ist ein Fehler beim Überprüfen deiner Lösung aufgetreten. Bitte versuche es später erneut, und kontaktiere uns, falls dieses Problem wiederholt auftritt."

Maybe it's due to the '#' which might get misinterpreted?

Hi Thomas, thanks for letting us know. I'll take a look.

Hi @vonk, can you submit the solution again? I changed something in the validation script.

Best, newton

Hi newton,

thank you for your efforts. Now the script accepts solutions again. Unfortunately mine is rejected as being wrong... Maybe I have a mistake in the solution string, which is quite long... However, as I managed to solve the second part of the challenge with this transposition result, it should be more or less correct. Perhaps I can send you a private message with my solution?

Best, Thomas

EDIT: Yes, I indeed had a mistake in my solution. After fixing this, the solution was accepted. Thank you newton, the validation script works fine!

Hi Thomas,

thanks for letting us know and congrats for solving the challenge!
