In number theory, a Heegner number (as termed by Conway and Guy) is a square-free positive integer d such that the imaginary quadratic field [] has class number 1. Equivalently, the ring of algebraic integers of Q [ − d ] {\displaystyle \mathbb {Q} \left[{\sqrt {-d}}\right]} has unique factorization .
New Zealand rabbits were not originally bred to be a domestic pet; they were bred for their fur and meat. Fryers are slaughtered at 8–12 weeks, [10] and older rabbits are sold as roasters. White rabbits are preferred for fur, because it's easier to dye. The rabbits with high grades of fur are used to make fur coats and fur trimmings.
