Wow, thank you very much! Just FYI, in the 20190602 version of the Metamath book, in the "write source" subsection (5.3.2) there is no option for /extract. On Saturday, April 6, 2024 at 6:45:50 PM UTC+2 ginogiott...@gmail.com wrote: > > Now I want to create this set_simplified.mm file. Mario

Thank you for all the answers, they are quite informative. Now I want to create this set_simplified.mm file. Mario Carneiro suggests to use a ""metamath aware" slicer". Is there such a slicer already created? I guess it is not as easy as just deleting, from set.mm, the subtheorems that are not

Thank you very much for the answer. Let us see if I understand this: Let us assume I take the 619 different subtheorems used in 2p2e4 (I get this number, 619, by doing SHOW TRACE_BACK 2p2e4 /COUNT_STEPS). These 619 subtheorems can be listed by doing show trace_back 2p2e4. The total number of

> 3. Is there some way to print/export to file the 12178 steps, and even the 5.9 x 10^12 steps, all at once? I ask this since running show trace_back 2p2e4 /tree gives me a tree, but with only the name of the subtheorems, not the steps themselves. And I have been unable to find a command that

> 1. In https://us.metamath.org/mpeuni/mmset.html#trivia, it is stated that "A longest path back to an axiom from 2 + 2 = 4 is *184 layers* deep". However, if I run show trace_back 2p2e4 /count_steps, it is stated that "The maximum path length is 84". Is there a typo somewhere? (84 != 184). Note

Hello, I am trying to understand 2p2e4, as an excuse to understand metamath better. I have a few questions: 1. In https://us.metamath.org/mpeuni/mmset.html#trivia, it is stated that "A longest path back to an axiom from 2 + 2 = 4 is *184 layers* deep". However, if I run show trace_back 2p2e4
