Much Greater
"Much greater" is used to indicate a strong inequality in which a is not only greater than b, but much greater (by some convention), is denoted a>>b. For an astronomer, "much" may mean by a factor of 100 (or even 10), while for a mathematician, it might mean by a factor of 10^4 (or even much more).
Euclid used the terminology that if a is greater than b and b is greater than c, then a is said to be much (or far) greater than c. In that sense, "far greater than" is synonymous with "greater than" for a dense set of ordered quantities.
