"The tetrofaxul is equal to 200!2 in Hyperfactorial array notation. Tetrofaxul can be thought as \"tetrofactorial\" of 200, which is, by analogy with expofactorial, means \\(f(n) = n \\uparrow\\uparrow (n-1) \\uparrow\\uparrow (n-2) \\cdots 4 \\uparrow\\uparrow 3 \\uparrow\\uparrow 2 \\uparrow\\uparrow 1\\). Thus, tetrofaxul can be represented as \\(200 \\uparrow\\uparrow 199 \\uparrow\\uparrow 198 \\cdots 4 \\uparrow\\uparrow 3 \\uparrow\\uparrow 2 \\uparrow\\uparrow 1\\). This is based on tetration. The term was coined by Lawrence Hollom."@en . "Tetrofaxul"@en . . . "The tetrofaxul is equal to 200!2 in Hyperfactorial array notation.
