Theorem a12study4 29117
 Description: Experiment to study ax12o 1875. The first hypothesis is a conjectured ax12o 1875 replacement (see ax12 2095 for its derivation from ax12o 1875). The second hypothesis needs to be proved without using ax12o 1875, if that is possible. (Contributed by NM, 7-Nov-1015.) (Proof modification is discouraged.) (New usage is discouraged.)
