Dear Friends,
I just created a mailing list devoted to Triangle Geometry.
The name of the list is Hyacinthos
(in honor of
Emile Michel Hyacinthe Lemoine).
By 7 March 2013, the number of messages had passed 21,600.
FORMERLY, subscriptions were available at HYACINTHOS. Messages have been preserved and made accessible by César Lozada. Many of these have been given new links in ETC, and others can be accessed by knowing the message number and following this example:
http://www.hyacinthos.99on.com/message.php?msg=25017
Simply replace 25017 by the message number that is shown in ETC. The same procedure works for ADGEOM messages, starting with
