Solutions of some problems in group theory can relatively easy be transferred to a sub- or supergroup if the index is small. Let G be a permutation group on the set {1,…,n}. -So one might try to find a series of subgroups G = H₀,…,Hₖ = Sₙ of the symmetric group Sₙsuch that Hᵢ₋₁ is a subgroup of Hᵢfor every i and transfer the solution of a problem for the symmetric group step by step to G. +So one might try to find a series of subgroups G = H₀,…,Hₖ = Sₙ of the symmetric group Sₙsuch that Hᵢ₋₁ is a subgroup of Hᵢ for every i and transfer the solution of a problem for the symmetric group step by step to G. Sometimes it is not possible to find such a series with small indices between consecutive subgroups. This is where subgroup ladders may make sense: |
