It is well-known that six-dimensional superconformal field theories can be exploited to unravel interesting featuresof lower-dimensional field theories obtained via compactifications. In this short note we discuss an application of 6d (2,0) theories to exhibit infinitely many classes of examples of four dimensional theories with Kramers-Wannier-like non-invertible symmetries.
