%N Odd composites (including 1 in the count) where the number 1 mod 4 equals the number 3 mod 4.

%C This odd composite race seems analogous to the prime number race

%F Beginning with 1, run separate counts for odd composites 1 mod 4 and 3 mod 4. When the count is equal, record the number for 1 mod 4.

%e a(1)=26829 is the first odd composite 1 mod 4 where the count 5238 is the same for 26835 3 mod 4

%Y Cf. A007350, A007351, A038691, A093181, A093182.
