There are 19 unique symbols used in the puzzle. Here's something I was working on.
GROUP 1 are the letters with 1 triangle blacked out
GROUP 2 are the letters with 2 triangles blacked out
GROUP 3 are the letters with 3 triangles blacked out
GROUP 4 are the letters with 4 triangles blacked out
The black symbols are the 19 that are used in the puzzle.
The RED symbols are ones that I thought were missing (to total 26). In other words, in group 1, the letter "C" doesn't have a mirror image in the
puzzle, so I added it in as an unused letter.
I used the 6 symbols at the bottom as ABC and XYZ. Unfortunately, when I plugged some of these letters into the puzzle, it was gibberish.
One problem is that "E" would be in group 1 and there aren't very many of those in the puzzle. In fact, with this map, "W" is the most used
letter... I think not...
I'm beginning to doubt the ABC XYZ assumption at the bottom of the page.
But I just wanted to put it out there to spark something.
I'm going to watch some TV with my husband now. Goodnight, all.
