I am trying to modify the following problem in the Open Library:
I am trying to write solutions that refer to the graphs pictured in the problems by their labels A,B,C,D. I construct four graphs and corresponding text strings $T1, $T2, $T3, $T4 describing their properties that I want to put in the solution. I would like the solutions to read something like: "Graph A has property $T1", "Graph B has property $T2", etc.
The problem is that the position of the graphs is randomized by the function checkbox_table, and I don't know how to recover the labels after the randomization takes place.
Any help is greatly appreciated!
