To be consistent with the + predType interface, this is done by coercion to FinGroup.arg_sort, an + alias for FinGroup.sort. Accordingly, all pointwise group operations below + have arguments of type (FinGroup.arg_sort) gT and return results of type + FinGroup.sort gT. + The notations below are declared in two scopes: + group_scope (delimiter %g) for point operations and set constructs. + Group_scope (delimiter %G) for explicit {group gT} structures. + These scopes should not be opened globally, although group_scope is often + opened locally in group-theory files (via Import GroupScope). + As {group gT} is both a subtype and an interface structure for {set gT}, + the fact that a given G : {set gT} is a group can (and usually should) be + inferred by type inference with canonical structures. This means that all + `group' constructions (e.g., the normaliser 'N_G(H)) actually define sets + with a canonical {group gT} structure; the %G delimiter can be used to + specify the actual {group gT} structure (e.g., 'N_G(H)%G). + Operations on elements of a group: + x * y == the group product of x and y. + x ^+ n == the nth power of x, i.e., x * ... * x (n times). + x^-1 == the group inverse of x. + x ^- n == the inverse of x ^+ n (notation for (x ^+ n)^-1). + 1 == the unit element. + x ^ y == the conjugate of x by y (i.e., y^-1 * (x * y)). + [~ x, y] == the commutator of x and y (i.e., x^-1 * x ^ y). + [~ x1, ..., xn] == the commutator of x1, ..., xn (associating left). + \prod(i ...) x i == the product of the x i (order-sensitive). + commute x y <-> x and y commute. + centralises x A <-> x centralises A. + 'C[x] == the set of elements that commute with x. + 'C_G[x] == the set of elements of G that commute with x. + < [x]> == the cyclic subgroup generated by the element x. + # [x] == the order of the element x, i.e., #|< [x]>|. + Operations on subsets/subgroups of a finite group: + H * G == {xy | x \in H, y \in G}. + 1 or [1] or [1 gT] == the unit group. + [set: gT]%G == the group of all x : gT (in Group_scope). + group_set G == G contains 1 and is closed under binary product; + this is the characteristic property of the + {group gT} subtype of {set gT}. + [subg G] == the subtype, set, or group of all x \in G: this + notation is defined simultaneously in %type, %g + and %G scopes, and G must denote a {group gT} + structure (G is in the %G scope). + subg, sgval == the projection into and injection from [subg G]. + H^# == the set H minus the unit element. + repr H == some element of H if 1 \notin H != set0, else 1. + (repr is defined over sets of a baseFinGroupType, + so it can be used, e.g., to pick right cosets.) + x *: H == left coset of H by x. + lcosets H G == the set of the left cosets of H by elements of G. + H :* x == right coset of H by x. + rcosets H G == the set of the right cosets of H by elements of G. + #|G : H| == the index of H in G, i.e., #|rcosets G H|. + H :^ x == the conjugate of H by x. + x ^: H == the conjugate class of x in H. + classes G == the set of all conjugate classes of G. + G :^: H == {G :^ x | x \in H}. + class_support G H == {x ^ y | x \in G, y \in H}. + commg_set G H == { [~ x, y] | x \in G, y \in H}; NOT the commutator! + <tt>H</tt> == the subgroup generated by the set H. + [~: G, H] == the commmutator subgroup of G and H, i.e., + <tt>commg_set G H</tt>>. + [~: H1, ..., Hn] == commutator subgroup of H1, ..., Hn (left assoc.). + H <*> G == the subgroup generated by sets H and G (H join G). + (H * G)%G == the join of G H : {group gT} (convertible, but not + identical to (G <*> H)%G). + (\prod(i ...)
