Proof step 2 from proof num-illi (previous step)

~9223372036854775808 ≤ i, i ≤ 9223372036854775807 ⊦ l2i(i2l(i)) = i

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ i ∈long → l2i(i2l(i)) = i
Proof step 4:
¬ i ∈long, ~9223372036854775808 ≤ i, i ≤ 9223372036854775807 ⊦ l2i(i2l(i)) = i

Rule argument
