Feb 16, 2022 at 9:31 | comment | added | bathalf15320 | Three questions. Are you interested in a proof? I can't find a definition of the outer nagel points. Are they the ones with barycentric coordinated $(a-b-c,c+a-b,a+b-c)$ etc. ? You have two triples of lines so they meet in 9 points. Is there a systematic way to specify the 6 that you mean? | |
