26 : Wiktionary, duodecentum. Under "Usage notes" it states:

Although duodecentum is the usual expression for 98, it is also possible to say nonaginta octo ("ninety-eight") or octo et nonaginta ("eight and ninety").

However the Latin cardinal numerals "appendix" article states:

Note that the compound numeral for 98 is not among the special cases, but instead is formed in the usual additive way.

The entry for undecentum states:

Although undecentum is the usual expression for 99, it is also possible to say nonaginta novem ("ninety-nine") or novem et nonaginta ("nine and ninety").

Regarding all unde- and duode- forms, the "appendix" article states:

The latter additive forms [such as triginta octo and octo et triginta] are possible, but are not found in Classical Latin as frequently as the subtractive form.

Along with duodeviginti and undeviginti, these are examples of discrepancies between the artificial Latin-like prefixes for -illion number-names and actual Latin number-names; see the discussion here.

28 : James Riordan, Metric Prefixes, 2002 (formerly at http://www.math.umn.edu/~riordan/prefixes.html). The author listsall of the official BIPM numeric multiplier prefixes, then states:

"Questionably scientific prefixes from the 1995 email response to the above by Tamara Munzner: .. zeppo .. harpo .. lotta .. lotto .. zuppa"

and gives etymologies similar to those at Numericana.

29 : The JARGON file, version 4.0.0 (July 1996), http://www.std.com/obi/Jargon/jarg400.txt. The relevant passage is:

[1993 update: hacker Morgan Burke has proposed, to general approval on Usenet, the following additional prefixes:   groucho 10^(-30) harpo 10^(-27) harpi 10^(27) grouchi 10^(30)   We observe that this would leave the prefixes zeppo-, gummo-, and chico- available for future expansion. Sadly, there is little immediate prospect that Mr. Burke's eminently sensible proposal will be ratified.]
