In this paper, we focus on the existence of symmetric λ-configurations with λ = 2, 3, and 4. Three new spatial configurations (v8)2 for v = 30, 31, and 32 are constructed. The existence of a spatial configuration (vκ)2 are updated for k ≤ 10. The existence tables for symmetric λ-configurations for λ = 3, 4,and small k are also given.
