Description: Perform the substitutions into the strict weak ordering law. (Contributed by Mario Carneiro, 31-Dec-2014.)
Hypothesis
Ref Expression
swopolem.1 ((φ (x A y A z A)) → (x𝑅y → (x𝑅z z𝑅y)))
Assertion
Ref Expression
swopolem ((φ (𝑋 A 𝑌 A 𝑍 A)) → (𝑋𝑅𝑌 → (𝑋𝑅𝑍 𝑍𝑅𝑌)))
Distinct variable groups:   x,y,z,A   φ,x,y,z   x,𝑅,y,z   x,𝑋,y,z   y,𝑌,z   z,𝑍
Allowed substitution hints:   𝑌(x)   𝑍(x,y)
