Tachyons and tachyonian systems. Generalisation of the special principle of relativity and an idea of six-dimensional space-time.

Appendix A  Rindler's derivation of LT

Presentation on 

Fifth International Conference on the Nature and Ontology of Spacetime  2018

 Dr E A B Cole mathematician who have published basic work on six dimensional relativity.

 His homepage  is closed, and he don't answer emails anymore, so perhaps he left this dimension.

Here you can find his introduction and reference to all his articles Among else he has written about Prediction of dark matter using six-dimensional special relativity

Dr Matej Pavsic physicist who have published on generalised LT, three times and tachyons
