Finding such a set of "a"'s with prime factors raised to an even power, is pretty non-trivial, and is not performed by the sieving clients or servers.
Initially wee derive a network in which nodes are primes and edges are drawn between
  • the two large primes in a double-partial relation, or between 1 and the single prime of a partial relation.
Then we run around looking for cycles in the network, which represent large primes that appear as squares when the two corresponding residues are multiplied together.
Multiply all relations together, divide by all squared large primes, and you turn lots of partials and double partials into full relations.
