(A stronger conjecture is that the number of tritangents is 72 or at most 68, with all values taken.) I will also put the problem into a larger context and discuss the known results and a few steps towards the proof of this conjecture.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Tarih: 20 Nisan 2018 Cuma, 15:40 Bilkent Matematik Bölümü Seminer Odası SA - 141 <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Konuşma öncesinde çay-kurabiye ikramı yapılacaktır. <o:p></o:p></p><p class=MsoPlainText> <o:p></o:p></p><p class=MsoPlainText><a href="https://twitter.com/Bilkent_math">https://twitter.com/Bilkent_math</a><o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>İ.
