The math as expressed in English in the original usenet post is ambiguous which confused me for a moment until I figured out what I was doing wrong. > Choose a 2-digit number, say 23, your “seed”. > Form a new 2-digit number: the 10’s digit plus 6 times the units digit. Here's where the ambiguity is, I interpreted this as (tens_digit+6)*units_digit so I did (2+6)*3=24 > The example sequence is 23 –> 20 –> 02 –> 12 –> 13 –> 19 –> 55 –> 35 –> … 24 != 20 so I had to walk back and figure out that they in fact meant tens_digit+(6*units_digit)
