Python programs for matrix computations of groups (F. Bianchi)

The software below allows to do matrix computations with representations of the two infinite groups

Γ = < x₀,...,x₆ | x_i x_i+1 x_i+3 = Id > and G = < x₀,...,x₁₂ | x_i³=x_i x_i+1 x_i+3 = Id >

Both groups act transitively on the vertices of Euclidean buildings of type Ã₂.
