comb_count_partitions_v1_1218484723_3404
Two athletes split a total of 4626 training minutes, each taking an odd number of minutes. Let $N$ be the number of such splits. A digital lock uses a function $f(a) = (3a^3 + a + 5) \bmod 1849$ to cycle through codes. A code $a$ is *cyclic of order 3* if applying $f$ three times returns to $a$, but not before. Let $n$...
