7.10.2.6 baumslagGroup

Procedure from library fpalgebras.lib (see fpalgebras_lib).

Usage:
baumslagGroup(m,n,d); m an integer, n an integer, d an integer

Return:
ring

Note:
- the ring contains the ideal I, which contains the required relations - Baumslag group with the following presentation
< a, b | a^m = b^n = 1 >
-d gives the degreebound for the Letterplace ring
- varying n and m produces a family of examples

Example:
 
LIB "fpalgebras.lib";
def R = baumslagGroup(2,3,4); setring R;
I;
==> I[1]=a*a-1
==> I[2]=b*b*b-1
