Defined in header <experimental/ranges/concepts>
template < class T, class U > concept bool CommonReference =   ranges::Same<ranges::common_reference_t<T, U>, ranges::common_reference_t<U, T>> &&   ranges::ConvertibleTo<T, ranges::common_reference_t<T, U>> &&   ranges::ConvertibleTo<U, ranges::common_reference_t<T, U>>;		(ranges TS)

The concept CommonReference<T, U> specifies that two types T and U share a common reference type (as computed by ranges::common_reference_t) to which both can be converted.
