Building off of the work of Kervaire–Milnor and Hill–Hopkins–Ravenel, Wang and Xu showed that the only odd dimensions n for which Sn has a unique differentiable structure are 1, 3, 5, and 61. We show that the only even dimensions below 140 for which Sn has a unique differentiable structure are 2, 6, 12, 56, and perhaps 4.
