Description of the results displayed in figure 5 for the bifurcation curves of straightened Gent materials. There are three different types of Gent materials (J_m=20, rubber; J_m=2.3, young artery; J_m=0.4, old artery) and four different angles (Θ₀=π/3,π/2,2π/3,π). Each curve is made of several pieces, each corresponding to the earliest bifurcation mode for a given value of ρ of the sector, with corresponding number of wrinkles k in the third column.

Jm	angle	number of wrinkles
20	Θ0=π/3	k=1 for 0.045<ρ≤1
