About This Design

"GRAHAM'S NUMBER"

"GRAHAM'S NUMBER"

"GRAHAM'S NUMBER," named after mathematician Ron Graham, is so vast that it holds the world record for the largest number ever used in a serious mathematical proof. Graham's number is much larger than other large numbers such as a googol and a googolplex. In fact, the observable universe is far too small to contain a written representation of Graham's number.

Lovely quality cards. Nice to get a real traditional Chrismassy theme in Australia, not the beach and Australian animals stuff. Excellent, would use again
