Dave Morice's November 1994 Kickshaws referred to a challenge suggested by the late Tom Pulliam. Based on the sum of all its letter-values (assigning A=1, B=2, and so on), each word has a certain value (DEBUT=52, DUCHY=61). Tom Pulliam had enquired of Dave Morice how long a list of consecutive numbers may be formed in this way. Dave pointed out that such a list would have to start with the word A(=1_ and be followed by AA(=2), BA (=3) and ABA (=4).
