This monograph addresses the problem of describing allprimitive soluble permutation groups of a given degree, withparticular reference to those degrees less than 256. Thetheory is presented in detail and in a new way using modernterminology. A description is obtained for the primitivesoluble permutation groups of prime-squared degree and apartial description obtained for prime-cubed degree. Thesedescriptions are easily converted to algorithms forenumerating appropriate representatives of the groups. Thedescriptions for degrees 34 (die vier hochgestellt, Sonderzeichen) and 26 (die sechs...
