a(n) = cardinality of the (ordered) list L_n defined inductively by: L₁ = {2}; if, reading from left to right, there is a member p of L_n such that prime(n+1) can be appended to the beginning or end of p so that their neighboring digits are equal, then append prime(n+1) to the beginning or end of p to obtain L_n+1; otherwise, add prime(n+1) to the end of the list L_n to obtain L_n+1.
