 A106385 Consider the Gaussian primes of the first quadrant a+bi, with a>0, b>=0, ordered as a sequence by the size of the norm and the size of a, as defined in A103431. The sum of these primes up to a+bi is divisible by a+bi. a(n) is the real part a of such a+bi. 2
 1, 2, 3, 1, 191 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 COMMENTS A106386 has the imaginary parts. LINKS EXAMPLE (1+i)+(1+2i)+(2+i)+3+(2+3i)+(3+2i)+(1+4i)+(4+i)+(2+5i)+(5+2i)+(1+6i)+(6+i)+(4+5i)+ (5+4i)+7+(2+7i)+(7+2i)+(5+6i)+(6+5i)+(3+8i) = (70+65i), (70+65i) / (3+8i) = (10-5i). This is the third number with the property, so a(3)=3. CROSSREFS Cf. A103431, A103432, A106386.
