Kalman's naming conventions for the length-11 EQ theses The following conventions for "naming" each of the 630 length-11 theorems of the classical equivalential calculus EQ first appeared in J. G. Peterson's The possible shortest single axioms for EC-tautologies, Report No. 105, University of Auckland, Department of Mathematics. They were later published as Appendix 1 of Kahlil Hodgson's Shortest single axioms for the equivalential calculus with CD and RCD, Journal of Automated Reasoning, vol. 20 (1998), pp. 283-316, where it is made clear that they are due to J. A. Kalman.           Each theorem of EQ is named using a string of two or three letters. The last letter gives the order in which the sentential variables (two occurrences of p, two of q, and two of r) occur in the formula, and the preceding letter(s) give its "bracket type", that is, the positions at which the E's and the sentential variables occur in it.  The details are as follows. Each length-11 formula is of the form Eαβ for some pair of formulas α and β.  If α and β are of the same length, the formula must be of one of the following four forms and its bracket-type is coded as shown: T = EEExxxEExxx U = EEExxxExExx V = EExExxEExxx W = EExExxExExx Otherwise, α and β are of different lengths. In that case, each of them must be of one of the following forms and the bracket-type of Eαβ is coded by the letter coding the bracket-type of α followed by the letter coding the bracket-type of β: A = EEEExxxxx B = EEExExxxx C = EEExxExxx D = EEExxxExx E = EExEExxxx F = EExExExxx G = EExExxExx H = EExxEExxx I = EExxExExx J = ExEEExxxx K = ExEExExxx L = ExEExxExx M = ExExEExxx N = ExExExExx O = EEExxxx P = EExExxx Q = EExxExx R = ExEExxx S = ExExExx Y = Exx X = x Each 11-symbol theorem of EQ contains two occurrences of p, two of q, and two of r. Up to alphabetical variance, there are 15 orders in which these may occur.  The full name for the theorem in question is then given by following the code letter(s) for its bracket-type with the code letter for the order in which the sentential variables appear in it: A = ppqqrr D = pqpqrr G = pqqprr J = pqrpqr M = pqrqrp B = ppqrqr E = pqprqr H = pqqrpr K = pqrprq N = pqrrpq C = ppqrrq F = pqprrq I = pqqrrp L = pqrqpr O = pqrrqp ILLUSTRATION 1. What is the name of the formula EEEpEqrrEqp? ANSWER.  It is of the form EEExExxxExx, and the letters in it occur in the order pqrrqp. Since EExExxx is of bracket-type P, Exx is of bracket-type Y, and pqrrqp is letter-order O, its name is PYO. ILLUSTRATION 2. What is the formula whose name is YQJ? ANSWER.  It's left-most part has bracket-type Y = Exx and its right-most part has bracket-type Q = EExxExx, so it itself has bracket-type EYQ = EExxEExxExx. The sentential letters occurring in it occur in the order J = pqrpqr. So YQJ is the formula EEpqEErpEqr.
