Abstract The staggered mode of solitons in polyacetylene which is first discovered by Sun et al. is one of the typical gap soliton studied in lattice system. Using a one dimensional damped and parametrically driven pendulum lattice, we have observed a stable staggered mode which can be explained successfully by a nonlinear Schrödinger equation under the multiple scale approximation.
