Closely packed conformations of helices formed on an ideal rope are considered. The pitch vs. radius relations which define a closely packed helix are determined. The relations stem from the turn-to-turn distance and curvature-limiting conditions. Plots of the relations are shown to cross each other. The physical sense of the crossing point is discussed.
