Comments

Mostly the subset of either A006145 or A039752 where both a(n) and a(n)+1 are squarefree (members of A005117), but also members of A178214. - Hans Havermann, Dec 16 2010, Dec 19 2010

Examples

			77 (7*11, with 78 = 2*3*13) is a member of both A006145 and A039752 (7+11 = 2+3+13) and so 77 is a member of this sequence.
7129199 (7*11^2*19*443, with 7129200 = 2^4*3*5^2*13*457) is a member of both A006145 (7+11+19+443 = 2+3+5+13+457) and A039752 (7+11+11+19+443 = 2+2+2+2+3+5+5+13+457) and so 7129199 is also a member of this sequence.
