Conway chained arrow notation, created by mathematician John Conway, is a means of expressing certain extremely large numbers.
The first rule is the core: A chain of 3 or more elements ending with 2 or higher becomes a chain of the same length with a (usually vastly) increased penultimate element.
After, to paraphrase Knuth, "much detail," the chain is reduced to two elements and the third rule terminates the recursion.

The notation is in particular relevant for chains of four or more elements.
Note that in the second case no paentheses are needed in the power notation, since right-to-left evaluation is implied, while the Conway chain needs them because otherwise the meaning is as in the first case.
A chain of length one is equal to the number itself.

John Horton Conway (born December 26, 1937, Liverpool, England) is a prolific mathematician active in the theory of finite groups, knot theory, number theory, combinatorial game theory and coding theory.
He invented a new number system, the surreal numbers, which are closely related to certain games and have been the subject of a mathematical novel by Donald Knuth.
Conway is professor of mathematics at Princeton University.

The Conway chained arrow can then be used: a chain of three elements is equivalent with the other notations, but a chain of four or more is even more powerful.
It is generally suggested that Knuth's arrow should be used for relatively smaller magnitude numbers, and the chained arrow or hyper operators for larger ones.
This is significant since the arrow operators are not commutative.

 Conway chained arrow - Definition up Erdmond.Com
:(1) A chain ''X→p→(q+1)'' of more than 2 elements not ending in 1 is the same as ''X→(X→(...X→(X)→q...)→q)→q'' (with ''p'' copies of ''X'').
Knuth's arrow and the hyper operators equate to 3-element chains: :''p→q→r'' = hyper''(p,r+2,q)'' = ''p^…^q'' with ''r'' up-arrows.
Conway's arrow doesn't help to express Graham's_number G succinctly, but: 3→3→64→2 < G < 3→3→65→2 Applying the first rule above, 3→3→64→2 = 3→3→(3→3→(...3→3→(3→3)→1...)→1)→1 with 128 threes.

For example, Conway's chained arrow notation explicitly defines what order repeated applications of itself should be evaluated in (it is right-to-left rather than left-to-right)!

When I am in a generous mood I consider Conway a hack who was too busy cranking out multiple books to take the time to proofread his work.
Conway didn’t seem to have any themes in mind for the book, so I’ll hold off on commenting on that topic until Paul Levitz comes on board in issue 62.
