Mathematicians define a random number as one that is
incompressible. In other words, it cannot be generated by an algorithm--a set
of instructions or rules such as a computer program--that is shorter than the
number

In`com*press"i*ble (?), a. [Pref. in- not + compressible: cf. F. incompressible.]

Not compressible; incapable of being reduced by force or pressure into a smaller compass or volume; resisting compression; as, many liquids and solids appear to be almost incompressible.

-- In`com*press"i*ble*ness, n.
