Trigintation refers to the 30th hyperoperation starting from addition. It is equal to $$a \uparrow^{28} b$$, using Knuth's up-arrow notation.[1]

Trigintation can be written in array notation as $$\{a,b,28\}$$, in chained arrow notation as $$a \rightarrow b \rightarrow 28$$ and in Hyper-E notation as E(a)1#1#1#1...1#1#1#b (27 ones).

Trigintational growth rate is equivalent to $$f_{29}(n)$$ in the fast-growing hierarchy.
