Hello,

for me this theorem goes through (with OBVIOUS), using the current distribution:

tlapm --version
1.4.5 (build 33809)

I'm afraid there must be a problem with your installation.

Hello

I'm reading simple examples on tlaps

https://sriramsami.com/tlaps/

the author said

that the theorem

THEOREM Transitive == 
    ASSUME 
        NEW X \in Nat,
        NEW Y \in Nat,
        NEW Z \in Nat,
        X > Y,
        Y > Z
        PROVE X > Z + 1


can be proved automatically with 
PROOF OBVIOUS

but it fails for me. Should i explicitly use a nonstandard solver i.e. CVC4?
