Lean formally certifies that the vectors f, π(a)f, π(b)f, π(ν)f are linearly independent for nonzero f in L²(ℝ) when |symp(a,b)| > 1 and 1, r, s are linearly independent over ℚ.

Lean-certified four-point HRT results for three lattice points and one off-lattice point
Lean formally certifies that the vectors f, π(a)f, π(b)f, π(ν)f are linearly independent for nonzero f in L²(ℝ) when |symp(a,b)| > 1 and 1, r, s are linearly independent over ℚ.
