Tridecation refers to the 13th hyperoperation starting from addition. It is equal to $$a \uparrow^{11}b$$, in Knuth's up-arrow notation.[1]

Tridecation can be written in BEAF and BAN as $$\{a,b,8\}$$, in chained arrow notation as $$a \rightarrow b \rightarrow 8$$, in the Graham Array Notation as $$[a,b,8]$$, and in Hyper-E notation as E(a)1#1#1#1#1#1#1#b.

Tridecational growth rate is equivalent to $$f_9(n)$$ in the fast-growing hierarchy.
