[cgal-discuss] Intersection on set of darts

Given a set of darts associated with a tetrahedron(3-cell) /t/ and a set of
darts representing a polyhedron(in combinatorial map representation) /p/. I
want to determine set of common 2-cells(or faces) between /t/ and /p/.

This problem seems to be a standard /set-intersection/ problem between 2
sets of darts(i.e.,* Set 1*: Darts representing faces of /t/, *Set 2*: Darts
representing faces of /p/)

I would like to know if there is any method already available in CGAL for
solving this problem or I should apply brute-force approach of comparing all
possible pairs of faces of/ p/ and /t/(represented by darts)?
