Moebius function

If we consider A0512270 and apply the Moebius function mu(n) to it we get a sequence of values: (-1,-1,-1,-1,-1),0,(-1),0,(-1,-1,-1,-1,-1,-1),0,0,(-1,-1,-1,-1),0,0,0,0,(-1,-1,-1,-1),0,(-1,-1),0,(-1, ... If we then group the similar values we get the above sequence. If we from a sequence A051270 subtract A046387 then we get numbers which represents zeros in values of \mu(n). These numbers are not semi Moebius primes. How 5,1,1,1,6,... is behaving - it would be nice to know?

Cf. A046387, A051270.
