Memory capacity is required to determine the number of page faults in a FIFO (First-In-First-Out) page replacement algorithm.

Let G be a graph with 100! Vertices, with each vertex labeled by a distinct permutation of the numbers 1, 2, …. 100. There is an edge between vertices u and v if and only if the label of u can be obtained by swapping two adjacent numbers in the label of v. Let y denote the degree of a vertex in G and z denote the number of connected components in G. Then, y + 10z =
