Let x0 of type ι be given.
Let x1 of type ιο be given.
Let x2 of type ι be given.
Assume H0: prim1 x2 x0.
Assume H1: x1 x2.
Apply unknownprop_7ba3c7fc1a64bc4a0aeed47bd1963f341f970e973cdb65321de4855f8cb88623 with x0, x1, x2, prim1 x2 (1216a.. x0 (λ x3 . x1 x3)).
Assume H2: prim1 x2 (1216a.. x0 x1)and (prim1 x2 x0) (x1 x2).
Assume H3: and (prim1 x2 x0) (x1 x2)prim1 x2 (1216a.. x0 x1).
Apply H3.
Apply andI with prim1 x2 x0, x1 x2 leaving 2 subgoals.
The subproof is completed by applying H0.
The subproof is completed by applying H1.
