In Hermann–Mauguin notation, space groups are named by a symbol combining the point group identifier with the uppercase letters describing the lattice type. Translations within the lattice in the form of screw axes and glide planes are also noted, giving a complete crystallographic space group. These are the Bravais lattices in three dimensions:
The 21st Operations Group was reactivated under Air Force Space Command's 21st Space Wing in 1992 and provided missile warning, space surveillance, and space control forces. On 24 July 2020, it was redesignated as Space Delta 2 and transferred from the Air Force to the Space Force on 21 October 2020. [ 1 ]

The area was part of Rancho La Ballona and later the Charnock Ranch (which grew lima beans, grain hay and walnuts). [4] [5] [6] Then, in 1939, the area was subdivided for the building of 1,200 single family homes by developer Fritz B. Burns, and it became one of the first examples of tract housing in the Los Angeles area. [5]
