kirby-paris but you append n copies of the grandparent too
you can do it where you append n copies of all x-parents too
1 (((())))
2 ((()())(()()))((()())(()()))

probably comparable to 2^^n for some smallish n
But wait! there's more naïve extensions to be done!
(1) = (((...))) with n nodes, where n is the turn # (1=e_0 for ordinal purposes)
1 (1())
2 (1)(1)
3 (())(1)
4 ()()(1)
5 ()(1)
6 (1)
7 (((((())))))
Oh boy, even without the prior extensions, this will be crazy
But wait! there's more!
(2) = (1(1(...))) with n nodes (2 = e_1 for ordinal purposes)
(m+1) = (m(m(...))) with n nodes
([hydra]) = ([next step in hydra]([next step in hydra](...))) with n nodes
([]) = (1)
Now, ([hydra]) = e_hydraOrdinal for ordinal purposes
That means that the next mess is...
(0,1) = ([([(...)])]) with n nodes (note: () is a node, [] is not). This is equivalent to z_0
1 (0,1())
2 (0,1)(0,1)
3 ([()])(0,1)
4 (1(1))(0,1)
...
@ordinal people: How good is this in the fgh? for instance, if I have f(0) = (), and f(n+1) = (0,1 f(n)), and g(n) = length of reduction of f(n), how good is g(n) in the fgh?
κ is measurable iff there is a nontrivial elementary embedding j:V→M (M transitive) with critical point κ
