![]() | Normal Surface Options |

The Surfaces options panel controls how Regina works with lists of normal surfaces.
The settings here are:
Specifies which coordinate system will be the default when you enumerate normal surfaces.
If checked, Regina will ask for confirmation whenever you try to enumerate normal surfaces without selecting embedded surfaces only. Regina asks for confirmation because non-embedded surfaces are typically much slower to generate, far more numerous, and Regina only offers very basic support for them.
Specifies which tab in the surface list viewer will first appear when you open a normal surface list for viewing.
Specifies which matrix (local or global) will first appear when you switch to the surface compatibility tab.
Determines when the surface compatibility matrices will be computed. If the number of normal surfaces is at most the given value, then Regina will compute compatibility matrices automatically. If the number of surfaces is larger, then Regina will not compute these matrices until you manually press the button.
