Interesting, I see what you mean. If you approach it in the more thematically consistent way it works. Interesting that that's the only set that doesn't work both ways.
Loge, if you are worried about a URL giving too much away, which I quite understand, you could always use tinyurl.com . It retains the link, but changes the URL to one of your own choice. Just a thought
Loge - your way is to assume the setter applied the order to the name to get the new order. The way I looked at it initially I was applying the order to what the setter had given to see if that gets you back to the name. Which works for all except the second.
Thanks SH. At last I now see what you and others were getting at, but I still don't get why all the other sets work both ways and this one doesn't. Either (a) it's a fortunate coincidence of the order of the presentations of the other sets or (b) I'm being extremely thick.
Here's a curiosity. I have now deduced the answer to 19 down, but for days I had cold-solved it as 'bootee'. Based on that being definition of marine and (ta)boo-tee being inappropriate topless beachwear, with 'a' as the extra letter.
