A pattern is referred to as spartan if it can be easily constructed with a slow salvo. What is implied by easily is quite subjective and normally means that the pattern is a constellation of spartan still lifes, that is sparse enough for them to be constructed in order without interfering with previously constructed islands. Though spartan patterns might also include spartan oscillators, but in practice they are not as important, because spartan patterns are primarily used in stable self-constructing circuitry.
Spartan still lifes
These still-lifes are commonly considered spartan: block, tub, boat, hive, ship, loaf, eater, long boat, pond. Snake is sometimes considered spartan too, but it's not that important, because in most conduits it can be replaced by an eater, which is easier constructible. Similarly, barge can be normally replaced by a boat. On the other hand, long boat is important not as a conduit component, but as the simplest color-changing 180-degree one-time reflector.
These oscillators are regarded spatan: blinker, beacon, toad. Spartan oscillators are normally considered only as an intermediate synthesis product in p2 slow salvo construction. Pulsar is technically spartan too, but it hasn't appeared useful enough to bother developing p3 or p6 slow salvo synthesis.
