Typos in the slides

[creepteks]

Hi there. So I was reading the slides but on slide 121, I got the feeling the there maybe some typos regarding the "what the prover would send back" to the verifier. The slide 121 states that "E(L(s)), E(L(s)), E(O(s)), E(L(s))" is being sent, while later on slide 124, it is stated that "the prover sends E(L(s)), E(R(s)), E(O(s)), E(H(s))". I'm having a hard time understanding what's going on, unless this is a typo. So would you please be kind to clarify on this?
I know this may not be the best place, but nice work on the talk. I really learned a lot.
