The white region corresponds to mono-stable designs, the light grey region is weakly bistable designs and the dark grey region is strongly bistable designs. The Miura-Ori are different in these four cases: (a) aII = 1.25aI, γI = 60°, (b) aII = 1.25aI, γI = 30°, (c) aII = 2aI, γI = 60° and (d) aII = 2aI, γI = 30°. b = aI for all four cases.
