Joycian trimentri is equal to \(\text g(3^{27},1,1,4,3,3)\) in Joyce's More Generalized Exponential Notation.[1][2][3] The value was created by Andre Joyce as a failed attempt to define the Bowersism trimentri. This number is approximately equal to {3,{3,27},1,2}, while the real value of trimentri is even larger, which is {3,3((1)1)2}.
