Searching for the Word for 100,000,000: Googleplex & Beyond

10,000 is a myriad.
100,000 is a lakh
10,000,000 is a crore

But nothing special after that except google and googleplex.

Anyone know a word for 100,000,000?

(The "Related Threads" listing for this sure is bizarre.)

100,000,000 is a squared myriad. So it could be a quadramyriad.

The number you listed is sayable as one hundred million, and sorry to be fussy, but the spelling of the number 'googol' is differerent from that of the search engine 'google, and so is that of the 'googol' in the number googolplex. If you're interested in expression of very large numbers, perhaps you might look at Prof. Knuth's up arrow notation.

That's three words.

Yes, "one hundred million" is three words; ok ##-## so (along the lines of your "squared myriad" suggestion) we can reduce the saying of 100,000,000 to two instances of one word (one of them singular form and one of them plural form): 'myriad myriads'.

Thinking metrically,
and inspired by the https://www.megamillions.com/ lottery (although the prize money has not been anywhere near a trillion dollars), you could call

100,000,000 = 1 hectomillion = 1 decibillion

Should be 10 decabillion I guess, otherwise it is a tenth of a billion.

100,000,000 = (0.1)(1 billion)

I have the ultimate reply to this alas I do not have access. Right now. Tomorrow morning.
Names, scope and context. The full nine yards, 27 feetish

Ok... so I fantasized 3 extra zeros into the number

In Chinese, the traditional power of ten groupings are by ##10^4## instead of the Western system of ##10^3##. So you have
十 = 10
百 = 100
千 = 1 000
万= 10 000
And then it repeats:
十万 = 100 000 (ten ten-thousands)
百万 = 1 000 000 (one hundred ten-thousands)
千万 = 10 000 000 (one thousand ten-thousands)
亿 = 100 000 000
They match up at ##10^{3\times4}##, or a trillion, which is 万亿.

Edit: If you want a word for 100 000 000 specifically, 亿 is yì, (which ironically, is a near homophone of the Chinese word for one: yī).

Looking into this further I quite like deca and deci, ten times a decamillion being a decibillion. However they have the flaw of differing only by one letter. Hekto sounds too much like "what the heck" or "heckle." It's ugly. Ini this case Latin and Greek are the same. Centi is possible but I think a decamillion is better than a centibillion. What do y'all think?

Maybe deka and deci. They are pronounced differently so that's quite legit.

I'd definitely go with Deca and Hecto, as that matches the real world convention of affixing ten- and hundred-
to the number name. A suffix that makes a number smaller only happens in fractions in English. Being clear is much more important than being pretty sounding. "Googol" itself is an example of that.

Beyond a trillion, however, I don't see the point of those names, as honestly scientific notation actually becomes clearer. You can say 4.819335x10²⁴ more easily then "Four Septilian, eight hectosextillion, one decisectillion, nine sextillion..."
