35 linear temperaments compatible with Genesis

I took the list of 319 11-limit linear temperaments which result from wedging three superparticulars together, and wedged each of them with the 43 tones of Partch's Genesis scale. Since the wedge product is distributive, two such wedge products will differ if and only if the associated linear product distiguishes the two tones in question. Hence I rather quickly found that there are 35 temperaments from this list which distinguish all 43 tones of Genesis. Since this is Partch, I sorted them by rms error (maximum error would have been better, but I haven't written the code for that) instead of badness. Here they are:
