PlantStar's Debut Notation is a notation created by User:Alpineer (originally PlantStarAlpineer0 when he made this notation),[1][dead link] which is currently ill-defined as will be explained in #Basic Bracket Notation and the creator clarified that it will never be defined.[2] Therefore the source has been deleted. It is based off of the number 48.

## Basic Bracket Notation

• [n] = 48n
• [1,n] = [48n]
• [n+1,1] = [n,48]

The original definition for this notation is obviously ill-defined because there is no rule applicable to [2,2], but later, DeepLineMadom pointed out in that user page and fixed the ill-definedness of the rule applicable to [2,2] by [m+1,n] = [m,48n].

### Multiple brackets

• [1][n]@ = [1,1,1,1,...(n "1"s)...,1,1,1,1]@
• [n][k]@ = [n-1][1,1,1,1,...(k "1"s)...,1,1,1,1]@

where @ is any string of brackets. Since Basic Bracket Notation is ill-defined, this notation is also ill-defined.

## Examples

• [2] = 482 = 2,304
• [10] = 4810 = 64,925,062,108,545,024
• [1, 1] = [481] = [48] = 4848 ≈ 1080.7
• [1, 2] = [482] = [2,304] = 482,304 ≈ 103,873.58
• [1, 10] = [4810] = [64,925,062,108,545,024] = 4864,925,062,108,545,024 ≈ 10109,154,691,756,057,088
• [1, n] = [48n] = 48(48n)
• [2, 1] = [1, 48] = [[48]] ≈ [1080.70] ≈ \(48^{10^{80.70}}\) ≈ \(10^{10^{80.93}}\)
