@vzn Hi vzn, Sir, hope you are well. yes I am aware of babai but can not get it as it uses Luks' work, If u remember , I had(have) a little knowledge about group theory, thus can't get Luks' which disable me to read babai's latest work. i have started Group theory, hope to get both Luks' and Babai soon.
@ThomasKlimpel I think , 1 column is not achievable, I missed a simple fact, sorry for wasting your time!
