I do not normally ask for help with puzzle solutions. However, there are times when I do get stuck (for a long time) on a part of a solution, and find myself exasperated enough to seek a hint or tip that will help me unlock a difficult block. The first (and only other) time I sought assistance, it was for the big band puzzle (puzzle 47 from Atlas 06 as I recall). This time it is for the revenge of salomon puzzle (puzzle 78 of Atlas 01).
The upper left corner has been giving me grief for about 3 years now, and I am tired of banging my head against the wall trying to solve the packing order. Would someone please provide me with a hint or tip as to how to solve this?
Thanks for any assistance provided.
