[GAP Forum] Create two groups using several vectors and then calculate the factor group between them.

[Hongyi Zhao]

Hi GAP team,

I try to understand the description given in this book [1] as shown in
the attached screenshot. As you can see, the author said that two
groups are created based on two sets of vectors, and then the factor
group was obtained. I'm very confused about this description, i.e.,
how we can create two groups using several vectors and then calculate
the factor group between them.

Regards,
