Abstract
The purpose of this paper is to characterize those symmetric Canter se ts which are sigma-symmetrically porous in terms of a defining sequenc e of deleted proportions. In contrast to other notions of porosity, a symmetric Canter set can be sigma-symmetrically porous without being s ymmetrically porous.
