Sets and Groups
Curly brackets { } are used to identify the elements of a set: {a,b,c} denotes a set of three elements.
Angle brackets are used in group theory to write group presentations, and to denote the subgroup generated by a collection of elements.

Famous quotes containing the words sets and/or groups:
“Music sets up ladders,
it makes us invisible,
it sets us apart,
it lets us escape;
but from the visible
there is no escape.”
—Hilda Doolittle (1886–1961)
“... until both employers’ and workers’ groups assume responsibility for chastising their own recalcitrant children, they can vainly bay the moon about “ignorant” and “unfair” public criticism. Moreover, their failure to impose voluntarily upon their own groups codes of decency and honor will result in more and more necessity for government control.”
—Mary Barnett Gilson (1877–?)
