In the Nov 1990 issue of Word Ways, Christopher McManus suggests finding ana-gram-mar chains in which word lengths increase and then decrease along the chain. Since jillions of ana-gram-mar chains are possible,k this is a good way to provide limits, but his idea can be improved by a more restrictive rule: increase or decrease in word length must be without halts, i.e., without inclusion of the chains of words of the same size. What is the longest chain with this new rule? Some fairly long ones are given below.
