Description: Inference chaining three syllogisms syl 17. (Contributed by BJ, 14-Jul-2018.) The use of this theorem is marked "discouraged" because it can cause the "minimize" command to have very long run times. However, feel free to use "minimize 4syl /override" if you wish. Remember to update the Travis "discouraged" file if it gets used. (New usage is discouraged.) |
