Bart Prenee (and David Chaum) both Len Sassamans doctoral advisors but well focus on Bart, co-authored papers with 9 of the 47 people in attendance at the #2 Reference in the Bitcoin whitepaper:
[2] H. Massias, X.S. Avila, and J.-J. Quisquater, Design of a secure timestamping service with minimal trust requirements, In 20th Symposium on Information Theory in the Benelux, May 1999.
One of the 47 in attendance was Bart Preneels academic advisor, Joos Vandewalle who was one of the 47 attendees of the whitepaper's [2] reference.
Add in the double spacing used in Lens writings, as well as Lens close relationship with Hal Finney, theres so many things that line up that in my opinion that keeps Len in the spotlight as a potential Satoshi Nakamoto candidate.
Len also owned a physical copy and was in attendance for the In 23rd Symposium on Information Theory in the Benelux which Im guessing was a couple years later.
Hes got a history of using British spellings on his twitter. The same words Satoshi used when communicating: flat, grey, bloody. Theres photographic proof but I cant add a screenshot for some reason.
Anyways, just more very interesting reading and a rabbit hole to go down. Ive got screenshots that show examples but not sure how to post them here.
