I gave Open 5.5 high your hint. This was the most interesting output:
'Side curiosity: many of the SECG/X9.62 seeds contain the ASCII text 4D696E6768756151 75 = "MinghuaQu" (a Certicom researcher), sometimes shifted by half a byte.'
I don't see any mention of that in the article.
this has been known for some time: https://bitcointalk.org/index.php?topic=5469657.10
That is mentioned in a years old post: https://saweis.net/posts/nist-curve-seed-origins.html
