Ramana Kumar comments on Generalized Heat Engine

[Ramana Kumar]

nit: “This transformation swaps $X_3^H$ with $X_7^H$ if $X_1^C$ is 1, and leaves everything unchanged if $X_1^C$ is 0.”

I think it actually swaps if $X_1^C$ is $0$ and leaves unchanged if it’s $1$.

nit: “swaps to coins”

missing ‘w’
