Hi All
I was away when this thread was going on, but I show a 'K' cane in Arculus and Walsh Walsh weights in the article I wrote for the 2006 PCA Bulletin titled 'Alphabet soup'.
In that article I explain how the 7/6 cane is made, and how as a result you can find the 'letters' A, B, C, D, H, J, K, V and numbers 1, 6, 7 and 9 at least! They are all accidental, but can be realistic.
