The googolminex is equal to 1/googolplex = 0.000...001 (googol zeroes, including the first one) or the reciprocal of a googolplex. The name was coined by John Conway and Richard K. Guy in The Book of Numbers, the same book where 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.
