I was playing with Zendo Set in my head, and came up with 21 possible koans with the BN, where we use three pyramids with the three usual sizes, and three possible colors of Red, Blue, and Yellow. (LLL,MMM,SSS)*(RRR,BBB,YYY) = 9 of one size and one color (LMS)*(RRR,BBB,YYY) = 3 of all sizes and one color (LLL,MMM,SSS)*(RBY) = 3 of one size and all colors (LMS)*(RBY,RYB,YBR,YRB,BRY,BYR) = 6 of all sizes and all colors I'm wondering how many koans ~without~ the BN there are. Let's see (LLS, LLM, LMM, MMS, LSS, MSS) times 9(?) otherwise valid color combinations... then color combinations would be the same, 6 x 9? David L.
