Annotating Don.Woods diagram (which is in the correct orientation) 2 3 --------------------- | @ # | | @ # | 1 |$$ @ # %%%%| 4 | $ @ %#% | | $ @ %% # | | $ %@ # | | $ %% @@# | | %%% #@@ | 4 |%%%% $ # @@@| 2 | $ # | | $ # | --------------------- 1 3 The duplicate piece in each tangle is: 1 2 3 4 Tangle 1 Blue Red Yellow Green Tangle 2 Yellow Blue Green Red Tangle 3 Green Yellow Blue Red Tangle 4 Red Green Yellow Blue
All 4 Tangles are the same puzzle, just colored differently.
Each has all 24 color permutations, plus a duplicate.
Each Tile also has a letter (A-Y) on the back, and a reference to the
Tangle that it occurs in. These letters appear to be for reference
only. I have found no corresponddence between the letterings in one
puzzle, and the letterings in another. I just use them as a convenience
for recording configurations, and sorting through the tiles.
