compact
 adj.

    Of a design, describes the valuable property that it can all be apprehended
    at once in one's head. This generally means the thing created from the
    design can be used with greater facility and fewer errors than an
    equivalent tool that is not compact. Compactness does not imply triviality
    or lack of power; for example, C is compact and FORTRAN is not, but C is
    more powerful than FORTRAN. Designs become non-compact through accreting 
    features and cruft that don't merge cleanly into the overall design
    scheme (thus, some fans of Classic C maintain that ANSI C is no longer
    compact).

compact
finite
isolated

   1.  (Or "finite", "isolated") In domain theory, an
   element d of a cpo D is compact if and only if, for any
   chain S, a subset of D,

   	d <= lub S  =>  there exists s in S such that d <= s.

   I.e. you always reach d (or better) after a finite number of
   steps up the chain.

   ("<=" is written in LaTeX as \sqsubseteq).

COMPACT, contracts. In its more general sense, it signifies an agreement. In 
its strict sense, it imports a contract between parties, which creates 
obligations and rights capable of being enforced, and contemplated as such 
between the parties, in their distinct and independent characters. Story, 
Const. B. 3, c. 3; Rutherf. Inst. B. 2, c. 6, Sec. 1. 2. The constitution of 
the United States declares that "no state shall, without the consent of 
congress, enter into agreement or compact with another state, or with a 
foreign power." See 11 Pet: 1; 8 Wheat. 1 Bald. R. 60; 11 Pet. 185.
