Maximum squared inverse distance from the origin to the hyperplane defined by hypercube points.

COMMENTS

Because it is not known if the squared inverse distances are always integers, this is a sequence of numerators (and the known corresponding denominators are all 1). The next two terms are conjectured to be 59 and 203 (distinct from sequences already in the OEIS).

FORMULA

a(n) = max_(m in M_n) m^(1) e^2, where M_n is the set of n X n nonsingular matrices with 1/+1 elements and e is the vector of all 1's.
