Abstract We discuss known maximal D-dimensional supergravities of two types: type I with G/H coset spaces and type II derived by compactification from higher dimensions without dualization. these have less manifest symmetries. In 4D and 6D in type I models we perform explicit gauge-fixing of local H symmetries in unitary gauges: symmetric. Iwasawa and partial Iwasawa. https://www.roamingfreesims.com/product-category/led-driver/
