A cyclical majority, as here defined, is a proper subset of the set of intransitive social orderings. Our usage follows Charles L. Dogson's use of the term ‘cyclical majority’ and is equivalent to David Klahr's ‘Type 2 intransitive social ordering’.

Curiously, Murakami and Riker have also erred when counting the number of possible weak preference orderings, although their errors differ in this case. Murakami states that if the number of alternatives is N, then the number of conceivable weak preference orderings is\(\mathop \Sigma \limits_{k = 1}^N \) k!. Murakami,Logic and Social Choice p. 13. Riker states that it is N!. William H. Riker, “Arrow's Theorem and Some Examples of the Paradox of Voting,”Mathematical Applications in Political Science, I, edited by John M. Claunch (Dallas: Southern Methodist University Press, 1965, p. 45. The following enumeration for N=3 is a counterexample to both statements: a1>a2>a3, a1>a3>a2, a2>a1>a3, a2>a3>a1, a3>a1>a2, a3>a2>a1, a1=a2>a3, a1=a3>a2, a2=a3>a1, a1>a2=a3, a2>a1=a3, a3>a1=a2, and a1=a2= a3. We conjecture that the correct number is the sum of all 2N-1 terms of the form (N1,\((N_1 ,\mathop {...}\limits^N N_R )\).
