Firstly on the drxx situation, I'm sorry to see him go, even though we had the odd run in on here. I haven't seen the comments but I'm sure Norah was well within her rights given his usual tone. Hopefully he can promise to be less forthright in future and Norah will let him back on.
I very much enjoyed the puzzle. Was tough, but I managed to get one quarter sketched in after solving about 10 clues and it all fell steadily from there.
I sympathise with drxx if he was criticising the relevant wiki entry, which makes little sense to me, and I have a maths background. I think I have the right string to highlight. But I am confused by the second and third strings, neither of which display any translation or rotation or reflection properties that I can see? Unless we leave the tail off the q. In which case it also meets the highlighting requirement?
