# Odd Steinhaus problem for finite sets

MathOverflow Asked by domotorp on November 30, 2020

Call a finite subset $$S$$ of the plane with an even number of points an odd Jackson set, if there is an $$Asubset mathbb R^2$$ such that $$A$$ meets every congruent copy of $$S$$ in an odd number of points.

Are there any odd Jackson sets?
