Ultronplex

The ultronplex is equal to $$u_{ultron,ultron}$$.


 * 1) Define $$u_{0,1}$$ as $$h_{ultron}(10,10,10,10,10,10,10,10,10,10)$$, using the hyperlicious function.
 * 2) Define $$u_{x,1}$$ as $$h_{ultron}(\underbrace{10,10,\ldots,10,10}_{u_{x - 1,1}})$$.
 * 3) Define $$u_{0,2}$$ as $$\underbrace{u_{u_{u_{\ddots_{ultron,1}},1},1}}_{10 \text{ copies of } u}$$.
 * 4) Define $$u_{x,2}$$ as $$\underbrace{u_{u_{u_{\ddots_{ultron,1}},1},1}}_{u_{x - 1,2} \text{ copies of } u}$$.
 * 5) Define $$u_{0,3}$$ as $$\underbrace{u_{u_{u_{\ddots_{ultron,2}},2},2}}_{10 \text{ copies of } u}$$.
 * 6) Define $$u_{x,3}$$ as $$\underbrace{u_{u_{u_{\ddots_{ultron,2}},2},2}}_{u_{x - 1,3} \text{ copies of } u}$$.
 * 7) Continuing this process, the ultron is $$u_{ultron,ultron}$$.
