I. 187 De la Beche..carries out the system more completely, calling the first, or superior order, Supercretaceous group, and applying the terms Cretaceous, Oölitic and Red sandstone to three groups into which he divides the second order, and giving the third the name Carboniferous group.

These sections are again divided into stages or groups.., and these again are often divisible into zones.
(iii)1883[see sense (ii)].1898Jrnl. Geol.

5. Math.
a. Orig., a set or system of operations so constituted that the product of any number of these operations is always itself a member of the ‘group’. Now more generally defined as: A set of elements, together with a single-valued associative binary operation, which is closed with respect to the operation and contains an inverse for each element and an identity element. (Except for the property of being closed these properties were formerly tacitly assumed.) [The sense is due to E. Galois, who used F. groupe (Bull. d. Sciences math., astron., etc. (1830) XIII. 435).]
1854Cayley Math. Papers (1889) II. 124 A set of symbols 1, α, β,..all of them different, and such that the product of any two of them..or the product of any one of them into itself, belongs to the set, is said to be a group. Note. The idea of a group as applied to permutations or substitutions is due to Galois.1893Forsyth Theory Functions 610 The Fuchsian groups conserve a line, the axis of x, or a circle, the fundamental circle; the Kleinian groups do not conserve such a line or circle, common to the group.1907M. Bôcher Introd. Higher Algebra vi. 82 The positive and negative integers with zero form a group if the rule of combination is addition... These same elements, however, do not form a group if the rule of combination is multiplication,..since zero has no reciprocal.1941Birkhoff & MacLane Surv. Mod. Algebra vi. 130 A group whose operation satisfies the commutative law is called a ‘commutative’ or ‘Abelian’ group.1958Sykes & Bell tr. Landau & Lifshitz's Quantum Mech. xii. 317 The set of all symmetry transformations for a given body is called its symmetry transformation group (or simply its symmetry group).1965Patterson & Rutherford Elem. Abstract Algebra ii. 31 Any element of a group S can be expressed in one and only one way in the form a {logicand} x, where a is a fixed element of the group.1969A. P. Cracknell Crystals ii. 65 All the operations of this type, combinations of a point-group operation and a lattice translation are said to make up a space group, and it is really a space group which is needed to describe the symmetry of a real crystal.
b. group theory, a branch of algebra concerned with the properties of groups and their applications, esp. in mathematical physics (e.g. to the investigation of symmetries in physical systems).
1898Proc. Calif. Acad. Sci. (ser. 3: Maths-Physics) I. iv. 29 In the application of group theory to problems of geometry and analysis, simple groups play the fundamental rôle.1919F. Cajori Hist. Math. (ed. 2) 335 A line-geometry and kinematics are elaborated, partly by the use of group theory, which are carried over to non-Euclidean spaces.1965J. C. Davis Adv. Physical Chem. iii. 75 The student of quantum mechanics and spectroscopy will find the structure of group theory beautiful and its utility exciting.
