Can you prove the claim given below? Inspired by [Lester's theorem][1] I have formulated the following claim: >**Claim.** Given any scalene triangle $\triangle ABC$ . Let $D$ be the reflection of incenter in sideline $AB$, and define $E$ and $F$ cyclically. The lines $CD$, $BF$, $AE$ concur in [X(79)][2] . Then, the two Fermat points , incenter and $X(79)$ lie on the same circle. [![enter image description here][3]][3] GeoGebra applet that demonstrates this claim can be found [here][4].
