Me: Yes, definitely - please submit it!
It would also be good to have a few examples of
sequences that give the trajectory of veraious
numbers under your map:
a(n) = a(n-1) + [smallest square > a(n-1)] if a(n-1) is not divisible 2 ,
else
a(n) = a(n-1)/2
such as 1--5--14--7--16--8--4 --2--(1) }
and
L2 = {11--27--63--127--271--560--280--140--70--35--71--152--76--3
8--19--44--22--...}
Give enough terms to fill 3 lines
Thanks!
