	OFFSET	`1,1`
	COMMENTS	`This sequence is finite because there is no prime a(6) since 233331,233333,233337,233339 are not prime.` `This is an initial subsequence of A048549, A065122, A088603, and A127889; and for any b, the base b analog of this sequence is an initial subsequence of the base b analog of each of these three sequences.

	EXAMPLE	`a(1)=2` `a(2)=23` `a(3)=233` `a(4)=2333` `a(5)=23333`
