  This report unravels frustration as a source of transient chaotic dynamics
even in a simple array of coupled limit cycle oscillators. The transient
chaotic dynamics along with the multistable nature of frustrated systems
facilitates the existence of complex basin structures such as fractal and
riddled basins. In particular, we report the emergence of transient chaotic
dynamics around the chaotic itinerancy region, where the basin of attraction
near the chaotic region is riddled and it becomes fractal basin when we move
away from this region. Normally the complex basin structures are observed only
for oscillatory states but surprisingly it is also observed even for
oscillation death states. Interestingly super persistent transient chaos is
also shown to emerge in the coupled limit cycle oscillators, which manifests as
stable chaos for larger networks.
