Trimaximal mixing
（重定向自Trimaximal）
Trimaximal mixing (also known as threefold maximal mixing) refers to the highly symmetric, maximally CP-violating, ![3 \times 3](/Images/godic/202502/17/ba0dffbf721ff09756465187f3aca3723042.png")
fermion mixing configuration, characterised by a unitary matrix (![U](/Images/godic/202502/17/4c614360da93c0a041b22e537de151eb3042.png")
) having all its elements equal in modulus
