Comment on “ On the chromatic number of simple triangle-free triple systems

We have found several errors in the paper [1] and the goal here is to present corrections to all of them. Equational references with square brackets [..] are with respect to the published version. Those with round brackets (..) are with respect to this comment. The notation is from [1]. There was a substantial error in the proof of [15] (in Section 11.4.1 of [1]) and a trivial error in the calculation to the proof of [8] (in Section 9 of [1]). These are corrected in Sections 1 and 2, respectively of the current note.
