Defined in header
std::greater<> is a specialization of std::greater with parameter and return type deduced.
 Implementation-defined strict total order over pointers

The implementation-defined strict total order is consistent with the partial order imposed by built-in comparison operators (
<=>, (since C++20)
>=), and consistent among following standard function objects:
- std::less, std::greater, std::less_equal, and std::greater_equal, when the template argument is a pointer type or void

The result of std::forward<T>(lhs) > std::forward<U>(rhs).
If the comparison between both arguments resolves to a built-in comparison operator for a pointer type, the implementation-defined strict total order is used for comparison after converting both arguments to pointers.
May throw implementation-defined exceptions.
The member type
is_transparent indicates to the caller that this function object is a transparent function object: it accepts arguments of arbitrary types and uses perfect forwarding, which avoids unnecessary copying and conversion when the function object is used in heterogeneous context, or with rvalue arguments. In particular, template functions such as std::set::find and std::set::lower_bound make use of this member type on their
