  Dear Peter, dear all,

  the loss of Sverre still less than one year ago; here I'd like to share a link 
to my talk slides presented at IAU Symposium 398 in Seoul, in June this year 
(2025), titled  "From NBODY1 to NBODY7: the Growth of Sverre’s Industry" . There 
are some nice pictures included, sorry I did not yet upload them to the 
notebook. The talk slides can be downloaded here:

  and the IAU proceedings paper here:

(0.5 MB, not all pictures included)

  Best wishes
  Rainer
