    Abstract: A rotation resistant rope comprising a central multi-wire strand of Seale's construction, an intermediate layer comprising a plurality of multi-wire strands closed in one operation around the central strand, and a covering layer of 10 multi-wire strands closed around the intermediate layer. Each intermediate and covering layer of strands has a direction of lay opposite to that of the other layer of strands. The outside strands and core are always laid opposite each other, but the wires within each of these strands may be Lang lay, although Regular lay is preferred, particularly for the outside strands. The 10 outside strands may comprise from 7 to 26 wires and all of the strands are identical. However, in a preferred construction each of the outside strands consists of 19 wires.
