That googol query reminded me of a large number notation in "The Lore of Large Numbers by (somebody) Phillips. It is attributed there to Leo Moser. He defines n'3=n^n ; n'4= (...((n'3)'3)...)'3 {n times} and so on. Then 2'4 = (2'3)'3 = 4'3 = 4^4 = 256 and 2'5 = (2'4)'4 = 256'4 = (...((256'3)'3)...)'3 {256 times} = ..... He calls this a Mega and then calls 2'Mega = Moser. "The largest number to have a special name." Indeed! This seems like it must be related to Ackermans generalized exponential, but I have been unable to relate it. For example, I find ack(2,2,n)=4, not matter how high the generalization. This is using: ack(a,b,0) = a^b (I cut it off here so I could extend further) ack(a,1,n) = a ack(a,b,n) = ack(a,ack(a,b-1,n),n-1) I did this a while ago using "bc". Is this right? Can anybody write a Mega or a Moser in terms of Ackerman's generalized exponential? Lew Mammel, Jr. ihuxv!lew
