The hyperfaxul.
~ 10{mega-3}(10{mega-3}2)
Moser's number, equal to 2 in a polygon where the number of sides is the already gigantic mega. The last 8 digits are ...80301056.
3{3{4}3}3
The second term in the sequence defining Graham's number.
(27{25}27){27{25}27 - 2}(27{25}27)
The troogathree, or booga applied 3 times to 3.
3{3{3{4}3}3}3
The third term in the sequence defining Graham's number.
2{2{2{2{2{2{2{12}3}3}3}3}3}3}3
Little Graham, the number that was actually the upper bound to the solution of the problem from which Graham's number arose.
3{3{3{3{3{3{3{3{4}3}3}3}3}3}3}3}3
G8, the first term in Graham's sequence larger than Little Graham.

fw+1(10)
The number that Denis Maksudov calls unaddom. It is equal to fw(fw(fw(fw(fw(fw(fw(fw(fw(f10(10)))))))))).

3 -> 3 -> 27 -> 2 in Conway's chained arrow notation. The number of times you would need to iterate the number of arrows to reach Conway's tetratri (which we will encounter later).

3{{1}}65
A BEAF lower-bound to Graham's number, starting with 3^^^3 instead of 3^^^^3.
g(64, 1, 1, 5, 3, 3)
A lower-bound to Graham's number using Joyce's g-function. In fact, if the g-function were defined so that g(a, b, c) was equal to c^ab instead of c^a-1b, then g(64, 1, 1, 4, 3, 3) would be exactly equal to Graham's number.
G64
Main article: Graham's number
Graham's number, the famous number that was devised as an upper bound to the solution of a problem in Ramsey theory.
10{{1}}100
The corporal, the first of Bowers' googolisms that is greater than Graham's number. It is reached by starting with 10^^^^^^^^^^10 (the tridecal) and iterating the number of arrows 99 times.
~ 9{{1}}116
The output of ioannis.c, or Ioannis' number. The last 8 digits are ...82688009.
G1,000,000
The forcal.
The Chained Arrow Range (10{{1}}10100 ~ {10, 10, 10, 100}
trooga(googol)
The bed. Trooga means booga applied n times to n (we saw some values of this earlier in the list).
fw+1(f8(8))
fw+2(2) in the fast-growing hierarchy. This is also equal to fw2(2), fw^2(2), fw^w(2), fe0(2), and (under my interpretation) fζ0(2), fη0(2), fphi(4, 0)(2), fphi(w, 0)(2), and even fΓ0(2). The last 4 digits are ...1248.
3 -> 3 -> 3 -> 3
Conway's tetratri. This number can be approximated by fw+1(fw+1(27)) in the fast-growing hierarchy, and is reached by iterating the number of up-arrows in the same way used to define Graham's number, only starting with 27 instead of 3^^^^3, and with (3 -> 3 -> 2 -> 3) - 1 iterations instead of just 64.
fw+2(10)
The number that Denis Maksudov named baddom.
4 -> 4 -> 4 -> 4
Conway's tetratet, the largest number mentioned in the Book of Numbers. It can be approximated by fw+2(fw+2(fw+2(256))).
10 -> 10 -> 10 -> 10
{3, 3, 3, 3}
Bowers' tetratri.
5 -> 5 -> 5 -> 5 -> 5
The fifth Conway number. It is approximately fw+3(fw+3(fw+3(fw+3(3125)))).
{4, 4, 4, 4}
Bowers' supertet.
{10, 10, 100, 4}
{10, 10, 100, 5}
{10, 10, 100, 6}
The boggol. Because the name is pronounced the same as "boggle", Bowers said of this number, "Boggles the mind, doesn't it?".
{10, 10, 100, 7}
The bagol. Bowers jokingly said "whatever you do, don't eat this many bagels".
{10, 10, 10, 10}
The general, or alternatively tetradecal.
The Linear Array Range ({10, 10, 10, 100} ~ {10, 100(1) 2})
{3, 3, 3, 3, 3}
The pentatri.
{7, 7, 7, 7, 7, 7, 7}
The supersept.
{8, 8, 8, 8, 8, 8, 8, 8}
The superoct.
{3, 3, 3, 3, 3, 3, 3, 3, 3, 3}
{10, 10, 10, 10, 10, 10, 10, 10, 10, 10}
The iteral.
fw^w(10)
The number that Denis Maksudov calls dekexom. This entry is used to discuss the order type ww in the fast-growing hierarchy, which represents the growth rate of Bowers' linear arrays, and the first part of my extension of Steinhaus-Moser notation (which is really just an offset form of Hyper-Moser Notation).
{3, 27(1)2}
Bowers' ultatri. It is a linear array of 27 threes.
