Declare pointer to 2D enum array

Consider the MNWE:

enum T {VALUE};

int main() {
    T T_arr[8][8];
    T** T_arr_ptr = T_arr;
}

Now this does not compile, saying

error: cannot convert T(*)[8] to T** in initialization

Without using auto, what would be the correct type for this pointer?

2D array names decays to pointer to first row of the array and hence it is of type pointer to array. Here T_arr is of type T(*)[8] after decay.
Change 

T** T_arr_ptr = T_arr;

to 

T (*T_arr_ptr)[8] = T_arr;
