Empirical for n mod 12 = 1: a(n) = 304*n + 35732 for n>11

Empirical for n mod 12 = 2: a(n) = 304*n + 32718 for n>11

Empirical for n mod 12 = 3: a(n) = 304*n + 33278 for n>11

Empirical for n mod 12 = 4: a(n) = 304*n + 31712 for n>11

Empirical for n mod 12 = 6: a(n) = 304*n + 34564 for n>11

Empirical for n mod 12 = 7: a(n) = 304*n + 33704 for n>11

Empirical for n mod 12 = 8: a(n) = 304*n + 34654 for n>11
