Generate the odd nonprime sequence with nonprimes labeled 1 mod 4 or 3 mod 4. Add count of nonprimes to sequence if just 1 nonprime congruent to 1 mod 4 occurs before interruption of a nonprime congruent to 3 mod 4.
EXAMPLE
a(3)=74 because 74 single nonprime runs occur below 10^3, each run interrupted by a nonprime congruent to 3 mod 4
