N2 - We prove that on each 2-step Carnot group with a corank 1 horizontal distributiontwo arbitrary points can be joined with a horizontal broken line consisting of at most 3 segments,while on every canonical 3-step Carnot group G with a corank 2 horizontal distribution two arbitrary pointscan be joined with a horizontal broken line consisting of at most 7 segments.We show thattwo arbitrary points in the center of G are joined by infinitely many horizontal broken lines with 4 segments.Here by a segment of a horizontal broken linewe mean a segment of an integral lineof some left-invariant horizontal vector fieldthat is a linear combination of left-invariant horizontal basis vector fields of the Carnot group.
