14:52:16 [LeeF]

chimezie: looked at algorithm in step 4 of 12.2.1 and tried to enumerate algebra constructs that arise from it

14:52:50 [LeeF]

... use a fold function to go from every combination of a left and right argument to 20 algebra expressions

14:53:05 [LeeF]

... idea would be to first list every permutation and then see which tests cover each
