Nov 14, 2021 at 19:47 | comment | added | Frieder Ladisch | I'm not sure what you mean, but maybe there is a misunderstanding here: I do not claim that the extraspecial group with $3^3$ elements has such a representation over the reals. I claim that when $G$ is a group of $3\times 3$ matrices over some field as in your question, then that field must contain primitive 3rd roots of unity. | |

Nov 14, 2021 at 19:28 | comment | added | Ian Gershon Teixeira | Everything in here looks great thanks so much! The one question I still have is could you give an example of the general result over (non algebraically closed) fields. For example could you give a 3 dimensional real representation of the extraspecial 3-group with $ 3^3=27 $ elements. I am a bit surprised that this exitsts. | |
