Googolminex is equal to 10-(10100) = 1/1010100 = (1010100)-1 = 0.000...001 (googol zeroes, including the first one), or the reciprocal of a googolplex. The name is constructed from The Book of Numbers by John Conway and Richard K. Guy,[1] where n-minex is defined as 10-n with a credit to Tadashi Tokieda is written ("googolminex" is not directly written.). In the same book they introduced their -illion scheme and chained arrow notation. It is a well-known example of a googolism which is a small number, or a micronym.

Garrett Wilkinson calls this the Wilkinson negative constant.[2]

Comparably, 1010-100, differing only by the placement of the minus sign, this time on the double exponent, is equal to ten to the power of one googolth; the googolth root of ten, which is very close to one (in fact only 2.303 googolths greater than 1; 1 + ln(10) 10-100).
