Is there a list of what they are? Preferably in hex?

To me, it looks like there are groups of 12 going on. 16-27, 28-39, 40-51, 52-63, 64-75, 76-87, and 88-98 are shades.

Am I right to assume duplicates? It appears number 88 black is the same as 1 black. Same for 98 white being the same as 0 white. I think the old and new 52 (red) are exactly the same.
