|  |  7.10.2.28 triangularGroup Procedure from libraryfpalgebras.lib(see  fpalgebras_lib).
 
Example:Usage:
triangularGroup(g,d); g an integer, d an integer
Return:
ring
Note:
- the ring contains the ideal I, which contains the required relations
- g gives the number of the example (1 - 14)
- d gives the degreebound for the Letterplace ring
 - varying g produces a family of examples
 
The examples are found in
Classification of the finite generalized tetrahedron groups
by Gerhard Rosenberger and Martin Scheer.
 The 14 examples are denoted in theorem 2.12
