Maximussexdecillion

A **maximussexdecillion** (also called a **sexdecillionplex** or **sexdecilliplexion**) is equal to 101051, or E51#2 in Hyper-E notation. It is equal to one followed by a Short scale sexdecillion zeros. It is 1051+1 digits long.

It is the sixth root of the Epstein system *octillia-illion* which is 106\*1051.

Writing down the full decimal expansion would take 1 short scale quattuordecillion (1045) books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).

## Names in -illion systems

In the short scale of the Conway-Wechsler system, it is called

It is slightly bigger than a maximusseptingennovemnonagintillion (or a septingennovemnonagintillionplex) (10102400).

This number is the sixth root of an Epstein system *tetracentillia-illion* which is 106x102403.

Writing down the full decimal expansion would take 1 septingenoctononagintillion (102397) books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).

Pekillion

A **pekillion** is equal to 103×103×10150+3. It is equal to one followed by 3×103×10150+3 zeros. It is 3×103×10150+4 digits long.

Writing down the full decimal expansion would take 3×103×10150-6+0.000003 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).
Picillion

A **picillion** is equal to 103,000,000,000,003, or E3,000,000,000,003 in Hyper-E notation. It is equal to one followed by 3,000,000,000,003 zeros. It is 3,000,000,000,004 digits long.

Writing down the full decimal expansion would take 3,000,000.000003 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).
Ominongularxihect

**Ominongularxihect** is equal to E100{#,#,2,1,1,...,2}100 (2 at position #+1). The term was coined by Sbiis Saibian. It has no actual definition, and hence is currently ill-defined.

Pentalogue

A **pentalogue** (or a **decabillionplexplexplex**) is equal to 10101010,000,000,000 = 1010101010, or E1#5 = EEEEE1 in Hyper-E notation. It is equal to one followed by a tetralogue (or a decabillionplexplex) zeros. It is equal to a power tower of five tens. It is 101010,000,000,000+1 digits long.

It is somewhat smaller than the Epstein system *decgigillio-illio-illion* which is 1,000,0001.000,0001,000,00010,000,000,000 .

Writing down the full decimal expansion would take 101010,000,000,000-6 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).
Notillion

A **notillion** is equal to 103×103×102,700+3. It is equal to one followed by 3×103×102,700+3 zeros. It is 3×103×102,700+4 digits long.

Writing down the full decimal expansion would take 3×103×102,700-6+0.000003 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).
Nonillionduplex

A **nonillionduplex** (also called a **nonillionplexplex**, **nonilliduplexion**, or **astronomical phosphophylphosphillion**) is equal to 10101030, or E30#3 in Hyper-E notation. It is equal to one followed by a maximusnonillion (also called nonillionplex or nonilliplexion) zeros. It is 101030+1 digits long.
It is slightly smaller than the Epstein system *quettillio-illion* which is 1,000,0001,000,0001030(the Quettillionth power of a million).

Writing down the full decimal expansion would take 10999,999,999,999,999,999,999,999,994 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).

Ogolgandingan

An **ogolgandingan** is equal to 1080×1,000,000,000,000, or E80×1,000,000,000,000 in Hyper-E notation. It is equal to one followed by 80 trillion zeros. It is 80×1,000,000,000,000+1 digits long.

Writing down the full decimal expansion would take 80,000,000 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).
Pentamillionplex

A **pentamillionplex** (also called a **maximuspentamillion** or a **hemidecamillionplex**) is equal to 105,000,000, or E5,000,000 in Hyper-E notation. It is equal to one followed by 5 million zeros. It is 5,000,001 digits long.

Writing down the full decimal expansion would take 5 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).

## Names in -illion systems

According to Landon Curt Noll's The English name of a number, hemigoogolgong is also known as:

one hundred milliamilliasescensexsexaginmilliasescenquinsexagintillion

In the Epstein system 105,000,000 is a hundred *tretrigintricentretriginoctaheckilillion*,a hundred times the 833,333rd power of a million.
Pentacthulhum

**Pentacthulhum** (also called **tethrarxihect**) is equal to E100#^^^#100 = E100#^^#^^#...#^^#^^#100 (100 #'s) in Extended Cascading-E Notation. The term was coined by Sbiis Saibian.

This expands to:

E100#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#^^#100

## Etymology

The name of this number is based on the words "pentation" and "Cthulhu".

Potillion

A **potillion** is equal to 103×103×101,500+3. It is equal to one followed by 3×103×101,500+3 zeros. It is 3×103×101,500+4 digits long.

Writing down the full decimal expansion would take 3×103×101,500-6+0.000003 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).
Limited system

The Limited System is a function used for mapping ordinals like ω to ψ=χ.

Here is the rules:

Rule 1: If ω^2,3Ψ = ω5^ω

Rule 2: If Ω,ω(4) after Ψ(9)

Rule 3: If Ψ=Ψ2

This will set up Γ3(α) into Ω(1) because Ω(1) has the bigger input.

Let Ψ be the collapser and Γ be the smaller input that does not make Ω=α(5). But what if ω=ψ(6), or approximately Ω(5)(9)? This can be fixed with the smaller ordinal being denoted as Ψ(-1) to make the smaller ordinal be small. The ordinal pattern Γ=α can be fixed to just ΨΩ, only because that the ω ordinal is ψ(2) in Collapsing Property of Ordinals, kind of like the Identity Property of Addition, where 1+0=1.
Ogolplex

An **ogolplex** is equal to 101080, or E80#2 in Hyper-E notation. It is equal to one followed by an ogol (100 short scale quinvigintillion) zeros. It is 1080+1 digits long.

It is the sixth root of an Epstein system *hectotredecillio-illion* which is 106x1080

Writing down the full decimal expansion would take 1074 books of 400 pages, with 2,500 digits on each page (except for the first, which would have 2,501).

## Names in -illion systems
