Non-abelian Groups

Baumslag groups

The Baumslag (respectively Baumslag-Solitar) groups are examples of two-generator one-relator groups. The first variante of this group has the presentation

<a, b | a^m = b^n = 1 > 

where m, n are natural numbers. The second variante of this group (the Baumslag-Solitar group) has the presentation

<a, b | b*a^m = a^n*b> 

where m, n are natural numbers. Computations of Baumslag groups.

Braid groups

For a natural number n the Braid group has n strands and n - 1 generators: g_1, g_2, ... , g_(n - 1) and relations: g_i * g_j = g_j * g_i for |i - j| >= 2 and g_i * g_(i + 1) * g_i = g_(i + 1) * g_i * g_(i + 1) for 1 <= i <= n - 2 Type Braid(n, [DegreeBound, LoopBound]) to calculate the Gröbner base.

Dihedral groups

The Dihedral group of degree n (natural number) has the presentation <a, b | a^2 = b^n = 1, aba = b^-1> Type Dihedral(n, [DegreeBound, LoopBound]) to calculate the Gröbner base.
