Abstract: A rope (210, 310) having a three-layered structure comprising a core layer, an inner layer and an outer layer, the core layer comprising one strand (225, 315), the inner layer comprising multiple strands (220) with an amount n and the outer layer comprising multiple strands (215) with an amount m, wherein n is an uneven number, and m is a number which has no common divisor with n, each strand is formed by multiple twisted metal filaments. By this structure fretting of the strands is reduced and the life time of the rope is improved. Also, the use of the rope in lifting application and an elevator system comprising such a rope are disclosed.
