Hi Larry -

good to see that.
I've taken a look into your text, and although there is a lot
of things I know from my own fiddlings, it was not easy for me
whaich of the 16 items was the crucial one, that step that
"no one before could solve"... I suspected it was around item 16

If you like you may look into my own treatize, where I -beginning
at the same path like you - arrived at a more general argument, which
too is not yet solved and either collatz implies this (or vice versa)
See
http://go.helms-net.de/math/collatz/aboutloop/collloopintro_main.htm
(this is html, but only poorly formatted, and one of my first
hobby-treatizes on numbers at all)

or

http://go.helms-net.de/math/collatz/Collatz061102.pdf

which is more compact, better formatted - I'm doing another edition of
that text, but this is only 50% rewritten (and I don't know whether I
find the time to really proceed... :( )
