Abstract
For every countable infinite group that admits as a homomorphic image, we show that for each , there exists a minimal action whose topological sequence entropy is . Furthermore, for every countable infinite group that contains a finite index normal subgroup isomorphic to , and for every , we found a free minimal action with topological sequence entropy , where . In both cases, we also show that the aforementioned minimal actions admit non-trivial independence tuples of size but do not admit non-trivial independence tuples of size for some .
