> 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:
