Integers which allow a unique modular cube root function. A positive integer n is in the sequence if x^3 (modulo n) describes a bijection from the set [0...n-1] to itself.

	OFFSET	`0,2`
	COMMENT	`Every member of the sequence is squarefree. If m & n are coprime members of the sequence, m*n is also a member.`
	EXAMPLE	`The number 30 is in the sequence because the function x^3 (mod 30) describes a bijection from [0...29] to itself. Thus every integer has a cube root, modulo 30.`
