SUMMARY
The discussion focuses on demonstrating that the field Q[i√6] is an intermediate field between Q and the field generated by Q[√2 - i√3]. The user seeks to establish the degree of the extension [F:Q[i√6]] and confirms that Q[i√6] contains Q. The relationship is further clarified by showing that Q[i√6] is contained in Q[√2 - i√3], as evidenced by the calculation of (√2 - i√3)² = 2 - 2i√6 - 3, which supports the argument for the intermediate field status.
