Abstract: Let be a measurable function satisfying and let be a sequence of integers satisfying . By the classical theory of lacunary series, under suitable Diophantine conditions on , satisfies the central limit theorem and the law of the iterated logarithm. These results extend for a class of subexponentially growing sequences as well, but as Fukuyama showed, the behavior of is generally not permutationinvariant; e.g. a rearrangement of the sequence can ruin the CLT and LIL. In this paper we construct an infinite order Diophantine condition implying the permutationinvariant CLT and LIL without any growth conditions on and show that the known finite order Diophantine conditions in the theory do not imply permutationinvariance even if and grows almost exponentially. Finally, we prove that in a suitable statistical sense, for almost all sequences growing faster than polynomially, has permutationinvariant behavior.
