Evolution of the semimajor axis a, eccentricity e, and inclination i for runs with an initial value of ﹩\vert V\vert =0.7﹩ for the third BH particle. The initial velocity of the third BH is in the x‐z plane, and the angle with the x‐axis is 60° (top left), 30° (top right), and 0° (bottom). Each panel shows the semimajor axis and the eccentricity of the inner (thick solid line) and outer binaries (thin dashed line).
