Chair, as I'm thinking this through, I'd also like one additional change to that, to say “also representing at least two political parties”. That way, you would not have just one group creating a quorum and not anybody else.
It's very unlikely to happen, but very clearly, a quorum has to be participation by members representing at least two parties and members from the opposition and from the government. So there should be at least two political parties represented in a quorum, in the definition of quorum.
