About: title not given

Some slight errors I think

Apparently Wild Rice – 3rd in GW’s projective geometry series – first page has something about the 9-pt circle here:

surprise omg, a translaton into English woud be nice … else i fear this gets sorted into oblivion.    for example what does a 9 point circle have to do with 4 points corresponding to 4 different centers of a triange have to do with each other.

They both contain the Euler line & extend the art to circles.  Some day I may translate when I get a tuit. You are welcome to try.  It was an interesting chain of thoughts which lead to that book this AM starting with randomness. cool
yesyes
