4 Parametrised Presentations

In this chapter we describe which pp-presentations for infinite coclass sequences (see [EL08]) are provided.

4.1 Provided pp-presentations

4.1-1 ParPresGlobalVar_2_1
‣ ParPresGlobalVar_2_1( global variable )
‣ ParPresGlobalVar_2_2( global variable )
‣ ParPresGlobalVar_3_1( global variable )

are lists consisting of the pp-presentations of the infinite coclass sequences of finite p-groups of coclass r, where the first number in the name gives the underlying prime and the second the underlying coclass. Each entry in the list is a record rec( rel, expo, n, d, m, prime, cc, expo_vec, name ) with m = 0 and expo_vec = [ ]. The record entries are of a form such that each record can be used as input for PPPPcpGroups (3.2-1); see there for more information.

4.1-2 ParPresGlobalVar_p_r_Names
‣ ParPresGlobalVar_p_r_Names( global variable )

gives the names of the infinite coclass sequences of finite p-groups of coclass r.
