Talk:Subgroup series

From Wikipedia, the free encyclopedia

[edit] Naming: Normal series, subnormal series

I'm using the term subnormal series for A_i \triangleleft A_{i+1} and normal series for A_i \triangleleft G, as I find these clear, and at least some sources Springer Encyclopaedia of Mathematics use this convention. There are visibly other conventions, and if someone more familiar with group theory usage would prefer another, I've no objection.
