Hi all,

It is known that

from these we can say that if

or vice versa.

The same is true for the relationship between (c and d) and (e and f)

I have found that by using permutations of the above.

From reasonably extensive computer modelling of n, it also appears that but I can't seem to relate that to the above. Is it obvious why and I'm just suffering brain-freeze?

Thanks for helping thaw me out
