Flan number 1 (Japanese: フラン数第一形態), the smallest of the six non-trivial Flan numbers, is the first version of Flan number coined by Japanese googologist 巨大数大好きbot.[1] The number is approximately \(10^{10^{10^{670,767}}}\).
Names in -illions[]
Using Saibian's generalization of Bowers' -illions, the number is approximately:[2]
