[GAP Forum] How to work in the two-element field F_2 in GAP.

[Jianrong Li]

Dear Forum,

I want to work over the field F_2 with only two elements 0, 1. 1+1=0.

I have matrices with entries 0, 1. The multiplication of the matrices are
over F_2.

I would like to define the default field as F_2. How could I do that in GAP?

I tried DefaultField(Z(2)). But it seems that this doesn't work.

Thank you very much.

Best wishes,
Jianrong.
