Topic: squeezing lemma


Hanting Zhang (Dec 25 2020 at 20:22):

Is there any lemma for $a \leq b \leq a$ implies $a = b$?

Eric Wieser (Dec 25 2020 at 20:28):

docs#le_antisymm I think?

Eric Wieser (Dec 25 2020 at 20:29):

tactic#library_search would find that

Hanting Zhang (Dec 25 2020 at 20:42):

Mhm. Thanks, I guess it'll take a while pick up on how to use everything. Didn't even know library_search existed. :o
