Particularly, we find that the maximal intensities of the multi-hump compactons approach to the natural base e as n →1+ . Moreover, we numerically study the stabilities and interactions of the single-hump and double-hump compactons such that some stable multi-hump compactons and elastic interactions are found for some small values of the parameter n.
