16ac is straightforward enough, just not the usual treatment of "new".
I have a solution which (IMHO) meets the instruction absolutely, but the language of components, let alone nine of them, is alien to that solution, and I think may be overcomplicating things. Like I say, once you've arrived at an answer which ticks all the boxes (and which, incidentally, produces similar results to the Stein/Bollywood entrants), there is no cause to look further. There might well be other solutions, but there's no way of checking and it then becomes like one of those late night "quiz" shows which invites you to come up with a boys name or somesuch. John is a boys name - it's good, but it's not right. We were thinking of Xavier.
If anyone wants to continue this line of thought off the board so as not to make life too easy for anyone who's struggling, then
