	OFFSET	`1,1`
	COMMENT	`Because 3-digit terms coincide with additive 3-dimensional primes A046713, it is interesting to start with 4-digit primes. All of them may use only zero and odd digits, with the unique exclusion 2003 with one even digit. Primes such that sum of any two_neighbor_digits is prime A086244.`
	LINKS	`Zak Seidov, Prime sum of three neighbor digits.`
	EXAMPLE	`1973 is a term because 1+9+7=17, 9+7+3=19, 7+3+1=11 and 3+1+9=13 are all prime.`
