Ivan Panchenko: Dictionaries such as Merriam-Webster give "septendecillion" instead of "septdecillion", this also fits to the Latin word "septendecim" and to Noll's system that is implemented in the Java program (although I have objections to Noll's system as well, it uses "millia", which is a plural form in Latin, instead of "milli"; "centillion", for instance, is composed as "cen-" plus "-tillion" in this system instead of "cent-" plus "-illion", so you get things like "cenoctotillion" instead of "cent(i)octillion", ugh!). I corrected the Mathematica program accordingly. https://www.merriam-webster.com/dictionary/septendecillion

Ivan Panchenko: Addendum to 4): On the other hand, if we take a system that can name any power of one million in a single word, we do not need to distinguish A060365 and A060366 in terms of the "American" and the dated "British" interpretation. Also note that A060365 starts with 1000 while A060366 starts with 1. Originally, A060365 and A060366 both included 1 but the description said "[m]ultiples of one million" rather than "[p]owers of one thousand". Now we have "[p]owers of one thousand" in A060366 and "[m]ultiples of one thousand" in A060365. This is a mess.
