Apparently it doesn't encode the order of the field correctly and always sets it to 2. Run the following to verify the error
sage:libgap(GO(4,4,1))
GO(+1,4,2)
or
sage:libgap(GO(4,GF(4),1))
GO(+1,4,2)
This is in 'SageMath version 8.1, Release Date: 2017-12-07' on ubuntu 18.04 apt installation.
Is there some other way to access native GAP commands in a worksheet that I'm overlooking?
In particular I'm just interested in evaluating the native gap command

sage: %gap Order(GO(1,4,4));
