% File     : FLD001-0 : TPTP v7.5.0. Released v2.1.0.
% Domain   : Field Theory (Ordered fields)
% Axioms   : Ordered field axioms (axiom formulation glxx)
% Version  : [Dra93] axioms : Especial.

% Source   : [Dra93]
% Names    :

% Status   : Satisfiable
% Syntax   : Number of clauses    :   27 (   3 non-Horn;   3 unit;  27 RR)
%            Number of atoms      :   73 (   0 equality)
%            Maximal clause size  :    4 (   3 average)
%            Number of predicates :    3 (   0 propositional; 1-2 arity)
%            Number of functors   :    6 (   2 constant; 0-2 arity)
%            Number of variables  :   50 (   0 singleton)
%            Maximal term depth   :    3 (   1 average)
% SPC      : 

% Comments : The missing equality axioms can be derived.
%          : Currently it is unknown if this axiomatization is complete.
%            It is definitely tuned for SETHEO.
% Bugfixes : v2.1.0 - Added different_identities clause.
