Three-loop corrections to hyperfine splitting in muonium, generated by the gauge-invariant sets of diagrams with muon and tauon loop light-by-light scattering blocks, are calculated. These results complete calculations of all light-by-light scattering contributions to hyperfine splitting in muonium.
三圈修正到μ子的精细结构分裂，由带有μ子和τ子圈光致轻散射块的规范不变集合图产生，已被计算出来。这些结果完成了μ子精细结构分裂的所有光致轻散射贡献的计算。
