Lightning's out! With all my -illions already created in the previous parts, now let's recap all the -illions from extended tier 4 to tier 6!

[RECAP]: EXTENDED TIER 4

There's so many different possibilities of tier 4 -illions from obscure websites. They are even organized in a sheet. It is always fun, so why not explain in this page?

There is another name for 15th tier 4 -illion which is familiar to most googologists: "pyrillion". This is also my co-official name alongside my more preferred "metillion".

I think this is a combination of "pyro" and -illion, but let’s get over it.

Intermediate googologists just remove "p" for tier 3 multiplicatives. This is what I did:

"The second letter is y, so I use the "hypillion" method. Just add an "o-" at the left of "pyr-" root!"

This coins "dakopyrillion", which is (10^46)-th tier 3 -illion, and several others.

But, is that it? Wrong. There are so many possible tier 4 -illion googologisms left to go. Here are some selected possibilities for tier 4.

Recap of my preferred system:

First off, we explain every single versions of CompactStar's systems. CompactStar has made two different systems of extended -illions from tier 4 to tier 6.

The first one is CompactStar's most recent system.

With CompactStar's systems out of a question, let's move on some more obscure systems.

Sigh, here I go. First off, BAT4423's system is easy to generalize, because you can use these words, previous tier 4 multiplicatives (*even to "marillions"), to make intermediate values.

There is one important amendment for the BAT4423's system: tier-3 multiplicative to "paptr" adds "o" before it instead of removing the "p", since the first letter is a "p", and the "p" already exists as the part of tier-3 multiplicative root.

And now, we reach the truly niche systems!

Here are the "999" limits for all of the eleven aforementioned systems. Underlined means it is changed to match with a respective systems.

The value of the 999th tier 4 -illion is: 10^(3*10^(3*10^(3*10^2,997))+3)

• My preferred system: bencebontarretillion

• CompactStar's latest system: beebecetillion

• Alternative CompactStar's latest system: bectbecetillion

• CompactStar's old systems: bubetarretillion

• BAT4423's system: betanenketillion

• MultiSoul's elongated CompactStar's system: buubetarreletillion

• Niche system #1: bencenonuperetillion

• Niche system #2: bencebetixetillion

• Niche system #3: borbontarretillion

• Niche system mashup: borbetixetillion

But there is one more system that is also owned by me, but it's much more obscure! This is so much fun!
