 A076340 Real part of the function defined multiplicatively on the complex numbers by 2->(2,0) and p->((floor(p/4)+floor((p mod 4)/2))*4,2-(p mod 4)) for odd primes p. 13

 OFFSET 1,2 COMMENTS a(A000040(n))=A076342(n); a(A001358(n))=A076343(n); a(A000961(n))=A076345(n); a(A005117(n))=A076347(n); a(A000290(n))=A076349(n); a(n)>0 for n<2187=3^7, a(2187)=-5816, A076341(2187)=-20047. LINKS EXAMPLE n=21: 21 = 3*7 = (4-1)*(8-1) = (4,-1)*(8,-1) -> (32-(-1)*(-1),-4+(-8)) = (31,-12), therefore a(21)=31, A076341(21)=-12; n=35: 35 = 5*7 = (4+1)*(8-1) = (4,1)*(8,-1) -> (32-1*(-1),-4+8) = (33,4), therefore a(35)=33, A076341(35)=4.
