%N a(1) = 5; a(2n) = smallest prime that is a right concatenation of a(2n-1) and a number with no insignificant zeros and a(2n+1) = smallest prime ending in ( the least significant digits) a(2n-1). Alternate left and right concatenation yielding primes.
%e a(4) = 3533 staring with a(3) =353 and a(5) = 33533 ending in a(4) = 3533.
