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
