“…But one can just apply the same method as the first two groups to solve out µ, λ, and Ψ 2 , which are (20), (21), and (13). Then, γ is derived from (70) as (22), U is derived from (74) as ( 26), Ψ 3 is derived from (80) as (14), ν is derived from (73) as (23), and finally Ψ 4 is derived from (81) as (15).…”
