We continue the study by Melo and Winter (2019)[3] on the possible intersection sizes of a k-dimensional subspace with the vertices of the n-dimensional hypercube in Euclidean space. Melo and Winter conjectured that all intersection sizes larger than 2 k− 1 (the “large” sizes) are of the form 2 k− 1+ 2 i. We show that this is almost true: the large intersection sizes are either of this form or of the form 35⋅ 2 k− 6. We also disprove a second conjecture of Melo and Winter by proving that a positive fraction of the “small” values is missing.
