This should be turned off since we are not doing proper field extensions at the moment, but clearly there's a radical somewhere. I guess we need one more integer as part of the genus 2 signature: the dimension of the radical.
To reproduce bug: Use BrahanaTest(5) on Brahana group 2.
By the way, I think this function is unique to you. I do not have such a command.
I'll let you close the issue if your code runs without issue.
This test is in Auto-Sandbox/tests/BrahanaTest.m. Easy to reproduce from there, I wont close it because its not fixed its low priority. Probably just needs a radical wrapping, which is an issue in TensorSpace I've got to deal with.

Test 2 seems fine now. Looks like Test 1 is producing an error. I'll fix that now.
Tests 1 and 2 are good now.
