   three common notions (so to speak) to power symbol manipulation, and a

  ==== System~0~
  
  This version follows _LoF_ and was the original proof of concept, so not
  much more needs to be said. There is one difference -- theorem *C5* is derived

  ==== _System~2~_
  
  Having shown that *C5* and *C6* form a basis, I now show that *C6* alone
  suffices. The derivation ends at the point where *c5.2* is proved, since
  that establishes that _Basis~2~_ is at least as powerful as _Basis~1~_.
