Research materials created and accumulated by Donald Cowan related to automorphisms. Includes computer printouts, diagrams of graphs, and notes. Also includes an undated letter to Donald Cowan from Ralph Stanton, Professor, University of Manitoba, regarding a note from Derrick Lehmer with a mathematical equation. The items in this file likely pertain to a paper by Donald Cowan titled, "The growth of network cost as a function of network size."

A letter from Ralph G. Stanton to Donald Cowan regarding graduate courses available at the University of Waterloo in the Faculty of Mathematics in Fall 1960. In the letter, Stanton requests that Cowan review a list of course descriptions (not included in this file) and select which he would be most interested in as required for a Masters degree. File also includes Donald Cowan's reply to Stanton outlining the five courses that held the most interest for him.

Two copies of a typed manuscript titled, "Counting algorithms for connected labelled graphs" by Donald Cowan, R.C. Mullin, and Ralph G. Stanton. The manuscript is twelve pages. This paper was presented at the sixth Southeastern Conference on Combinatorics, Graph Theory, and Computing held at Florida Atlantic University in Boca Raton, Florida between February 17-20, 1975. This paper was subsequently published in the Proceedings of the sixth Southeastern Conference on Combinatorics, Graph Theory, and Computing, pages 219-231. Also includes correspondence related to the submission of the paper to the conference.
