This dataset contains the look-up tables of the 12,923 new quadratic APN instances in dimension eight found by utilizing linear self-equivalences and/or applying the switching construction of [EP09]. A preprint of our paper is available at arxiv: C. Beierle and G. Leander. New instances of quadratic APN functions. 2020. Together with the 23 APN instances listed in [EP09], the 8,157 APN instances constructed by the QAM method [YWL14], and the 10 APN instances presented in [WTG13], those are all 8-bit APN functions up to CCZ-equivalence known so far.
