	OFFSET	`1,2`
	COMMENT	`Conjecture: except for 1,2,3,4, this is the nonzero values of A066362.`
	EXAMPLE	`10 is in the sequence because phi(10) = 4, and no larger m has phi(m) < 4. phi(12) = 4; it is not smaller.`
	CROSSREFS	`Cf. A036913, A000010, zeros of A066362.` `Adjacent sequences: A122954 A122955 A122956 this_sequence A122958 A122959 A122960` `Sequence in context: A097602 A126794 A011862 this_sequence A078769 A064375 A037229`
