Tritri（又称“特利特利”<ref>Googology Wiki (zh). 特利特利 [Tritri]. ''(EB/OL), Googology Wiki''. https://googology.fandom.com/zh/wiki/特利特利</ref>,“吹吹”），最经典的不能简单地用科学计数法表示的大数，通常由[[高德纳箭头]]或 [[BEAF]] 定义。

=== 定义 ===
<math>\begin{align} \mathrm{Tritri}\  & = 3 \uparrow\uparrow\uparrow 3 \\ & = 3\uparrow\uparrow3\uparrow\uparrow3 \\ & = 3\uparrow\uparrow(3\uparrow3\uparrow3) \\ & = 3\uparrow\uparrow(3\uparrow27) \\ & = 3\uparrow\uparrow 7625597484987 \\ & = \left.\begin{matrix}3^{3^{3^{3^{\cdots}}}}\end{matrix}\right\}7625597484987 \\ \end{align}</math>

<math>\begin{align} \mathrm{Tritri}\  & = \{3,3,3\} \\ & = \{3,\{3,2,3\},2\} \\ & = \{3,\{3,\{3,1,3\},2\},2\} \\ & = \{3,\{3,3,2\},2\} \\ & = \{3,\{3,\{3,2,2\},1\},2\} \\ & = \{3,\{3,\{3,\{3,1,2\},1\},1\},2\} \\ & = \{3,\{3,\{3,3,1\},1\},2\} \\ & = \{3,\{3,27,1\},2\} \\ & = \{3,7625597484987,2\} \\ & = \left.\begin{matrix}3^{3^{3^{3^{\cdots}}}}\end{matrix}\right\}7625597484987 \\ \end{align}</math>

=== 历史 ===
2013 年，Tritri 诞生，<ref>Bowers, J. (2013). Infinity Scrapers. ''(EB/OL)''. http://www.polytope.net/hedrondude/scrapers.htm</ref>命名者为 [[BEAF]] 创始人 Jonathan Bowers。

2015 年 7 月 24 日，Tritri 被 HypCos 称作 Trientri，<ref>HypCos (2015). Numbers from linear array notation. ''(EB/OL)''.  https://stepstowardinfinity.wordpress.com/2015/07/24/lan-numbers/</ref>LAN 表示为 <math>s(3,3,3)</math>。
