Ricky,
the arrow in the notation denotes John Conway's chained arrow notation which is much much larger than knuth's up-arrow notation.
In fact, The chained-arrow notation here is pretty huge, although I'm not sure I really got the concept of the notation in full.

]]>If n-1 is divisible by almost all prime numbers, n+1 should be prime.
Thats a hypothetic conclusion.
By hypothetic, do you mean one that remains to be unproven?
And what is meant by most?
]]>Let n=6->6->6->6->6
Let n1 equal to the smallest number apart from zero and one which is a perfect square, cube, fourth, fifth, sixth and nth power.
n1+1 is a prime number.
Proof:- n1-1 is divisible to almost any prime number, because of the fact that (a^n-b^n) is divisible by (a-b).
I don't understand your 6->6->6->6 notation.
I also don't see how stating n1-1 is divible by almost any prime number proves n1+1 is prime.
