[r-t] Scientific triples

[Alexander Holroyd]

I never understood why this particular method was chosen from the many 
available using this group.  Can someone enlighten me?

For elegant simplicity I think I would choose instead "quick-six triples" 
(PABS will explain), or for an exciting blue line what about e.g.
