COMMENT

Sequence contains many primes.

A007775 without the first term. Strictly speaking, the sequence should include the 1, because 1=7-6 and -6 = 24 mod 30. [From R. J. Mathar (mathar(AT)strw.leidenuniv.nl), Sep 25 2008]

EXAMPLE

7+0=7, 7+4=11, 7+6=13, 7+10=17, 7+12=19, 7+16=23, ...

PROGRAM

(Perl) $a = 0; while ((($a % 30 == 0 or $a % 30 == 4 or $a % 30 == 6 or $a % 30 == 10 or $a % 30 == 12 or $a % 30 == 16 or $a % 30 == 22 or $a % 30 == 24) and eval("print \"\".(7+\$a).\" \"; return 0; ")) or ++$a) { }
