A period-52 temperament described as the 988 & 2444 temperament for the 2.5.11.13.29.31 subgroup, and tempers out the comma 2.29.31 [-5 -52 52], which means 5 periods are equal to 31/29. Called so because there's 52 playing cards in the traditional deck. 1789edo does not support it as 1789 is a prime number, and therefore is not divisible by 52. | |||
