  Space Group
The Space group is led by Professor Bill Hillier and involves seven key members of staff.
Joint projects with the Bartlett's Management group are concerned with refurbishment of occupied buildings, and virtual construction; and there is collaboration with the lighting research of the Environment group in the CANDLE and 'Urban lights' projects.
As a complement to the Space Syntax Laboratory's interests in networks and movement, Professor Philip Steadman is exploring the morphology of building envelopes, and new techniques for enumerating 'possible built forms'.

  Science Fair Projects - Space group
The space group of a crystal is a mathematical description of the symmetry inherent in the structure.
The word 'group' in the name comes from the mathematical notion of a group, which is used to build the set of space groups.
The set of all 230 possible space groups in 3D is made from the combination of the 32 crystallographic point groups with the 14 Bravais lattices which belong to one of 7 crystal systems.

The space groups in three dimensions are made from combinations of the 32 crystallographic point groups with the 14 Bravais lattices which belong to one of 7 crystal systems.
In 3D there are 230 crystallographic space group types, which reduces to 219 affine space group types because of some types being different from their mirror image; these are said to differ by "enantiomorphous character" (e.g.
A space group with a screw axis is in the same crystal class as one with a corresponding pure axis of rotation.

Always Track Space Group Symmetry: Monitor space group symmetry during interactive changes to cell contents (e.g., continuously as the bond length slider is used) instead of only computing it after the change is completed.
Group: Set the space group to exactly symmetrize to when the Symmetrize button is pushed.
The values in the disabled fields are predetermined by the space group to which the structure is constrained (see Figure 37).
