If the conic is tangent to the ramification lines one obtains a family of curves of degree 2n with 3n singularities of type A_{n-1}. We calculate the fundamental group and Alexander polynomial for any member of this family and for some deformations of it.10 pages, 2 figuresAlgebraic Geometry14H20; 14H30; 14E20text
