The 3-Dimensional Matching (3DM) decision problem takes as input three sets \(A, B\), and \(C\), each having size \(n\), along with a set \(S\) of triples of the form \((a, b, c)\) where \(a \in A, b \in B\), and \(c \in C\). We assume that \(|S|=m \geq n\). The problem is to decide if there exists a \(3 \mathrm{DM}\) matching, i.e. a subset of \(n\) triples from \(S\) for which each member of \(A \cup B \cup C\) belongs...

Problem 6: Take an infinite set A of naturals, i.e. AC N. Create the choice function aA : NN by setting oA(n) = n-th integer in A. For example, if A is the set of prime numbers, then oA(0) 2, OA(1) 3, aA(2) = 5, oA(3) = 7, OA(4) = 11, ect. We also define the position function TA : AN as follows.
