### Abstract

In this paper we estimate Banach-Saks index of intersection of two spaces with symmetric bases from below by indices of these spaces. We also show on example of Orlicz spaces that we can’t estimate Banach-Saks index of intersection in the same way from above.

#### Keywords:

Banach-Saks index, symmetric basis, Orlicz space.
