	OFFSET	`2,1`
	COMMENT	`A123505 records the lengths of runs. A123506 uses the second zero.`
	FORMULA	`Extract argument from (1/n)^z, z = (1/2 + i*14.134725142...). a(n) = 1 if arg is between 0 and 180 deg.; and = 0 if otherwise (n=2,3,4...).`
	EXAMPLE	`a(8) = 1 since (1/8)^z = (.353553..., Angle 115.943...deg.)`
