Googolminex is equal to 1/googolplex = 0.000...001 (googol zeroes, including the first one) or the reciprocal of a googolplex. The name is described by Sbiis Saibian, who refers to The Book of Numbers by John Conway and Richard K. Guy, where Nminex is defined as 10-N with a credit to Tadashi Tokieda is written. In the same book they introduced their -illion scheme and chained arrow notation. It is a rare example of a googolism which is a small number, or a micronym.
Garrett Wilkinson calls this the Wilkinson negative constant.
