Hi,
as far as I know, the mapping is described by a formula:

The letters {A,B,C} are interpreded as numbers {0,1,2}, respectively.
Given the crystal_id, the letter can be computed as crystal_id%3 and the number in front of the letter is just crystal_id/3

(a%b is the integer modulus operation and a/b is the integer division)

Example:
cyrstal_id = 10
crystal_id % 3 = 1 -> A
crystal_id / 3 = 3

consequently: crystal_id 10 = 3A

I think this scheme agrees with this picture:
