Comment on Bells Theorem Versus Local Realism in a Quaternionic Model of Physical Space

I point out critical errors in the paper Bells Theorem Versus Local Realism in a Quaternionic Model of Physical Space by J. Christian, published in IEEE Access. Christians paper in fact contains several conflicting models. None of them form counterexamples to Bells theorem. Most of Christians paper is devoted to a model based on the detection loophole due to Pearle (1970).
