The quartification model is an SU(3)4 extension with a bi-fundamental fermion sector of the well-known SU(3)3 bi-fundamentalfication model. An alternative "flipped" version of the quartification model is obtained by rearrangement of the particle assignments. The flipped model has two standard (bi-fundamentalfication) families and one flipped quartification family. In contrast to traditional product group unification models, flipped quartification stands out by featuring leptoquarks and thus allows for new mechanisms to explain the generation of neutrino masses and possible hints of lepton-flavor non-universality.
四重化模型是一种SU(3)⁴扩展，具有著名的SU(3)³双基本化模型的双基本费米子扇区。通过重新排列粒子分配得到了四重化模型的一种替代“翻转”版本。翻转模型有两个标准（双基本化）家族和一个翻转四重化家族。与传统的乘积群统一模型不同，翻转四重化的突出特点是具有轻子夸克，因此允许有新的机制来解释中微子质量的产生以及轻子味非普遍性的可能迹象。
