[v1.51] August 4th, 2025: Yet another hiatus? Now we have the time for a brief continuation of the Collapsing-E notation.
[v1.51.1] August 5th, 2025: Continued working at the seventh sneak peek of the Collapsing-E notation.
[v1.51.2] August 7th, 2025: Reorganized the plan by adjusting the ExE number range after tethrathoth.
[v1.51.3] August 25th, 2025: Continued working at the seventh sneak peek of the Collapsing-E notation futher to the Solidus-Extended Cascading-E notation level (continue at sneak peek 8).
[v1.51.4] September 11th, 2025: Now we finally dashed your final plan for the Extended Collapsing-E notation, and fixed typo "sneak peak" into "sneak peek"!
[v1.51.5] October 16th, 2025: Just a month of break, I finally planned to devise the entire ExE root chart from the guppy regiment to the tethrathoth regiment!
[v1.51.5_1] October 17th, 2025: Created the first few parts of the root chart.
I plan to create some extensions of the Extensible-E system by Sbiis Saibian.
Collapsing-E notation (&E) [Predicted FGH ordinal level BHO (ψ0(ε(Ω+1)))] (definition completed, number list in progress)
Extended Collapsing-E notation (x&E) [Predicted FGH ordinal level ψ0(Ω_ω)] (in progress)
Hyper-Extended Collapsing-E notation (#x&E) [Predicted FGH ordinal level ψ0(Φ_1(0)), where Φ_1(0) is the least omega fixed point] (planned)
Inaccessible Collapsing-E notation (I&E) [Predicted FGH ordinal level (unknown)] (planned)
Comprehensive lists
Legend:
★ (Star) = The milestone number (typically at the terminal point of each regiment or squad). Varies depending on the number list.
✪ (Super-Star) = The big milestone number (typically at the terminal point of each major regiment, super regiment, mega regiment, etc.). Varies depending on the number list.
☆ (Featured Star) = Recommended number. May vary depending on the number list, but all milestones up to tethrathoth (E100#^^#100) are featured numbers.
⍟ (Popular Star) = Widely used in googology community. Do not vary depending on the number list.
✳ (Dictionary Star) = Have a well-established names in dictionary, either they have some definitions related to the googolism or not, depending on the external sources.
✪ (Filled Descriptions) = The number has more than many descriptions. Only used in the complete number list.
✡ (Last and/or Largest Number) = The last or the largest number of a specific category, zone, the ExE notation level, or the set of numbers with that property.
✤ (Old Number) = The number was invented somewhere from 1920 (the year of googol naming) to 1983 (the year of Sbiis Saibian's birth).
✥ (Pioneer Number) = The number was invented somewhere before 1920.
