sLLLLLL
6L 1s, named archaeotonic in TAMNAMS, is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 6 large steps and 1 small step, repeating every octave. Generators that produce this scale range from 171.4 ¢ to 200 ¢, or from 1000 ¢ to 1028.6 ¢. Scales of this form are always proper because there is only one small step.
Names
TAMNAMS suggests the temperament-agnostic name archaeotonic as the name of 6L 1s. The name was originally used as a name for the 6L 1s scale in 13edo.

Temperaments
There are two notable harmonic entropy minima with this MOS pattern. The first is tetracot, in which the generator is identified with 10/9 and four generators make a 3/2. These produce very soft tunings of archaeotonic, ranging from 4:3 in 27edo to 7:6 in 48edo. The second is known as didacus, which is at a basic level the temperament in the 2.5.7 subgroup defined by 3136/3125, where two generators make 5/4 and five make 7/4, and produces very hard tunings, ranging from 4:1 in 25edo to 7:1 in 43edo; it has various extensions that span portions of this range, including roulette and mediantone to the no-twos 19-limit, and hemithirds (along with its 5-limit microtemperament restriction luna) and hemiwürschmidt to the full 7-limit.
The 6L 1s pattern also houses a temperament of the 11th and 13th harmonics, i.e. Bluebirds, where the generator is identified with 143/128; for example L=7 s=4 (46 edo) is such a scale.
