For a common notion of symmetry in Euclidean space, G is the Euclidean group E (n), the group of isometries, and V is the Euclidean space. The rotation group of an object is the symmetry group if G is restricted to E + (n), the group of direct isometries.
Watering-Provide a bowl of fresh drinking water at all times. Desert Spiny Lizards donât drink often, however providing a water bowl is recommended. Some keepers mist their dragons once to twice a week with a spray bottle. Lighting-Since this is a diurnal species, it requires two light bulbs.exas Spiny Lizards spend the majority of their time in trees, though they can be observed on fence posts or walls in areas inhabited by humans.

But a cactus is known for being able to live with very, very little water! Cactuses (sometimes also called cacti) are a type of plant called a succulent, and are best known for living in hot, dry places like the desert, where they do not get a lot of water. Cactuses do need some water to survive, but can get along with a lot less than most plants. One reason cactuses can get along with less water is because they donât have leaves, so the water a cactus drinks does not evaporate as much as the water other plants drink.
