Finding nonclassical counterexamples

Here is a random argument! (Premises above the line; conclusion below it)

  • ---------------
  • ¬(s ∧ ((u ∧ k) → b))

Give a counterexample to this argument in the LP matrix, if there is one!

Note that the matrix can change from one argument to the next, so stay alert!
