Abstract

In this paper we, prove that if the product X n of a space X has certain tightness-type properties, then the space of permutation degree SP n X has these properties as well. It is proven that the set tightness ( T -tightness) of the space of permutation degree SP n X is equal to the set tightness ( T -tightness) of the product X n .
