I cannot find an operator "RO" so that given a list, say {a,b,c}, RO[&&,{a,b,c}] produces a && b && c

This is kinda tricky, but to understand why, evaluate FullForm[a && b && c] and you'll see that it's not multiple And statements but just one long one. – Searke Apr 01 '19 at 18:18
If it were multiple operations, you'd use Fold. – Szabolcs Apr 01 '19 at 18:27

BTW the typical way is And @@ {a,b,c}. – Szabolcs Apr 01 '19 at 18:28

@Szabolcs code is the short form of Apply[And, {a, b, c}] – Bob Hanlon Apr 01 '19 at 22:12
