The first use of this strain designation was UM-HET3

Miller, R. A., C. Chrisp, and A. Galecki. 1997. CD4 memory T cell levels predict lifespan in genetically heterogeneous mice. FASEB Journal 11:775-783

UM-HET3 mice are neither an F1 nor an F2 hybrid. (An F2 hybrid is made by crossing males and females of the same F1 hybrid stock.) The correct designation is a "four-way cross."

Publications from the NIA Interventions Testing Program

The first ITP paper also referred to these mice as UM-HET3, using this strain designation regardless of the site at which the mice were produced.  See:
