Talk:Crossing number inequality

In the section on variations, in the expression

:$\backslash frac\{f\_d^\{d+2\}(\backslash Delta)\}\{(d+3)^\{d+2\}f\_\{d-1\}^\{d+1\}(\backslash Delta)\}$

is $f\_d^\{d+2\}(\backslash Delta)$ supposed to be read as a power $(f\_d(\backslash Delta))^\{d+2\}$?

Either way, it is not clear. MWinter4 (talk) 17:21, 18 July 2024 (UTC)
