A complex non-realizable gaussoid

All gaussoids on n le 4 are real-realizable (and hence complex-realizable) because the B_n-orbit of each 4-gaussoid contains a realizable gaussoid and the action of B_n preserves real realizability. The complex non-realizable gaussoid on n=5 from Example 8.2 is contained in the Macaulay2 file vamos.m2.
