# Little graham's number, Graham's number and the Graham-conway-number

Sbiis Saibian desbribes on his site in section $3.2.9$ the "little-graham-number" He claims that Graham used this number (much smaller than "Graham's number") in his proof, and Gardner published "Graham's number" and finally he mentions the version with fours instead of threes, called the "Graham-conway-number".

• What is known about the history of these $3$ numbers ?
• Saibian's web site seems to explain the situation in great detail, so perhaps you could say what you are looking for that he does not cover. – MJD Dec 1 '14 at 14:38
