Y class

Immigration and Customs Enforcement will accept only a “Y” class ticket, or a full-cost coach fare, which can often cost more than first class.

During these years Dr. Studer helped James Naismith invent basketball, hired a young mechanic named Henry Ford for $2 a night to teach a Y class in ironworking.

Thirdly, let us suppose that we have subdivided the xy′-Class, the x′y-Class, and the x′y′-Class in the same manner, and have, in each case, assigned the Inner Cell to the Class possessing the Attribute m, and the Outer Cell to the Class possessing the Attribute m′.

Fourthly, let us suppose that we have subdivided the x′-Class in the same manner, and have assigned the South-West Cell to the x′y-Class, and the South-East Cell to the x′y′-Class.

Hence we see that we have assigned the West Half to the y-Class, and the East Half to the y′-Class.
