A myriad is equal to \(10^4\) = 10,000.[1][2] It was first used by the Ancient Greeks and became a basis of the Greek myriad system. It also has its own name in eastern Asian naming systems, although in English its name is "ten thousand". In googology, it is used in Donald Knuth's -yllion system.
In Roman numerals, it was written as ↂ or X̅.
It is also called Wan (萬or万 in Chinese) or man (まん in Japanese)[3] in Japanese and Chinese counting systems.
The outdated prefix myria- means multiplying by 10,000.
10,000 can be called "garhundred" using the gar- prefix.
Nirvana Supermind calls this number Grand zeroogol and zero-millenol, and it's equal to Q<10,zeroogol> = Q<10,1000> in quick array notation[4].
Aarex Tiaokhiao calls this number qoodrol, 4-noogol[5], or goonaolex, and it's equal to a(10,100,0)x[2] in Aarex's Array Notation.[6]
Wikia user NumLynx gave the name tetraplex for this number, coined in analogy to the tetralogue. [7]
Username5243 calls this number niloogolplex, niloogolnilex or gooquol, and it's equal to 10[0]10[0]100 = 10[1]4 in Username5243's Array Notation.[8]
DeepLineMadom calls the number boogolplex, boochilol, and trooqol, and is equal to 10[2]10[2]100 = 10[3]4 in DeepLineMadom's Array Notation.[9][10] It is not to be confused with the much larger Bowers' boogolplex, which is {10,10,{10,10,100}} in BEAF.

Note: The readers should be careful that numbers defined by Username5243's Array Notation are ill-defined as explained in Username5243's Array Notation#Issues. So, when an article refers to a number defined by the notation, it actually refers to an intended value, not an actual value itself (for example, a[c]b = \(a \uparrow^c b\) in arrow notation). In addition, even if the notation is ill-defined, a class category should be based on an intended value when listed, not an actual value itself, as it is not hard to fix all the issues from the original definition, hence it should not be removed.
