Proof step 17 from proof lebs-dom-remove-refsize0 (previous step)

gstore[m] = groupblock(gndx, lax, (range ri | m).size), ri[key] = @(m, m0, m1), inv(gstore \ ginval), ri-cons(ri, nodes(gstore ↓, ginval)), key ∈ ri, m ∈ gstore ⊦ ∃ adr. adr ∈ ri ∧ adr.lnum = m

User applied rule exists right

And closed the goal!

Rule argument

Additional information

Used simplifier rules: ⊦ key ∈ ri ∧ ri[key] = adr → adr ∈ ri; (s)% ⊦ @(m, m0, m1).lnum = m; (s) Used terms: @(m, m0, m1)
