Abstract: The relationship between the Fermat number and the T function generated by single cycle T-function's maximal periodic sequence were found. The 2-adic complexity of the kth coordinate sequence and the state output sequence were studied. Values and bounds of the 2-adic complexity were obtained. It is shown that the two sequences generated by the single cycle T-function cannot form l-sequences.

Key words: Fermat number, sequence, 2-adic complexity, single circle T-function
