Fraenkel \(\cal N48\): Pincus' Model XI | Historical notes
Description: \(\cal A=(A,<,C_0,C_1,\dots)\) is called anordered colored set (OC set) if \(<\) is a linear ordering on \(A\)and the \(C_i\), for \(i\in\omega\) are subsets of \(A\) such that for each\(a\in A\) there is exactly one \(n\in\omega\) such that \(a\in C_n\)
Parameter(s): This model does not depend on parameters
