Non-Adaptive 12 Identical Balls

Thought provoking..

"None of the balls weighed twice are weighed with any of the other twice weighed balls". I think you meant to type this (corrected weighing) 1st weighing ABCDE v FGHIJ 2nd weighing GCJE v AIHK 3rd weighing BEI v GDL

But neither of these produce a solution.

(your weighing) If the result is LRS => Either A or D can heavy or J can be Light. So Cant say.

(Corrected weighing) If the result is LRS => Either A can heavy or J can be Light. So Cant say.

But I still like the idea. Good luck!!
