COMMENTS
| This is the special case k=6 of sequences with mutual residues -k. In general, a(1)=k+1 and a(n)=min{m | m>a(n-1), mod(m,a(i))=-k, i=1,...,n-1}.
An infinite coprime sequence

FORMULA
| a(1)=7, a(2)=13, a(n)=-1+a(1)*a(2)*...*a(n-1)
a(n)=a(n)^2+6*a(n)-6, n>3

MAPLE
| a:=proc(k, n::nonnegint) option remember; if n<3 then RETURN(n*k+1); fi; if n=3 then RETURN(a(k, 1)*a(k, 2)-k); fi; a(k, n-1)*(a(k, n-1)+k)-k; end; seq(a(6, n), n=1..8);
