    Let \(RRC_ n\) be the class of all regular real closed fields (RRC- fields) of zero characteristic with Galois group G(F) having a system of generators \(\sigma_ 1,\sigma_ 2,...,\sigma_ n\) such that any linear order L on F is the restriction of the unique order on \(\tilde F^{\sigma}\) for some involution \(\sigma \in \{\sigma_ 1,\sigma_ 2,...,\sigma_ n\}.\) The main result is: The elementary theory \(Th(RRC_ n)\) of the class \(RRC_ n\) is decidable for any \(n\in \omega\).
