what is the differenvce in naming your seed to naming your nomad? Is there a specific pattern to lettring and numbering to configure your planet? someone give me a hint? I would like to know? I am not interested in other peope's seeds only in finding out how to name a seed.

The seed defaulting to your Nomads name is a convenience. Unless Craneballs discloses their seeding algorithm (or someone went through the pain of trying out a great lot of seeds ...), no one will be able to tell you, if using certain combinations of characters / numbers in specficied positions in the seed will result in certain planetary features.
